The following is an example of a single-chip frequency circuit design experiment report: ** 1. Purpose of the experiment ** The purpose of this experiment is to design a spectrum circuit based on a single-chip computer, to realize the analysis and display of the input signal spectrum characteristics, to master the application principle of single-chip computer in spectrum analysis, as well as the design and tuning methods of related circuits. ** 2. Experiment Principle ** 1. ** Basics of Spectral Analysis ** - Spectral analysis was a technique that converted a time-domain signal into a frequency-domain signal to obtain information such as the frequency composition and magnitude of the signal. For a complex periodic signal, it could be decomposed into a series of sinewaves of different frequencies. - In this design, the input signal was processed by a specific circuit module, and then the processed signal was collected and analyzed by the single-chip computer, and finally the frequency spectrum information of the signal was obtained. 2. ** The role of the single-chip processor in the frequency spectrum circuit ** - The single-chip computer was the core of the control system and was responsible for coordinating the work of each circuit module. For example, control the collection of signals, the execution of processing algorithms, and the display of spectrum results. - Choose the appropriate model of the single-chip (such as the STM32F103 single-chip, etc.), which has sufficient processing power, appropriate I/O interface, and rich internal resources (such as timers, ADC, etc.) to meet the design requirements of the spectrum circuit. 3. ** Circuit module composition ** - ** Program Controlled Attenuation module **: For example, the HMC624 and other program controlled Attenuation modules are used to adjust the amplitude of the input signal to adapt to the input range requirements of the subsequent circuit modules. This was because the magnitude of the input signal might vary greatly, and it needed to be weakened to a suitable range to prevent the signal from being saturated or damaging the subsequent circuits. - ** filtering module **: filtering the input signal through a filter to remove unwanted frequency components or noise. According to the design requirements, different types of filter such as low-pass, high-pass, band-pass, or band-stop filter can be selected. - ** Mix module **: Like the ADL5801 Mix module, it will mix the input signal with the signal generated by the local oscillation, and convert the high frequency signal into an intermediate frequency signal. This helped to reduce the frequency of the signal, making it easier for subsequent processing and analysis. - ** Fixed gain amplifier module **: For example, the ADL5611 fixed gain amplifier module can amplify the intermediate-frequency signal after mixing to increase the signal amplitude and meet the requirements of detection and ADC acquisition. - ** Detector module **: The ADC 8310 detector module is used to detect the amplified intermediate frequency signal and convert the AC signal into a direct current signal so that the ADC of the single-chip computer can collect it. - ** Phase-locked loop chip (such as ADF4351)**: It is used to generate the system sweep frequency signal generator to generate a stable local oscillation signal. The output signal frequency range can be set according to the design requirements (such as 35 to 400MHZ). ** 3. Experimental Equipment ** 1. Single-chip development board (including the selected single-chip, such as STM32F103 development board). 2. The circuit modules included a program controlled decay module, a filter module, a frequency mixing module, a fixed gain amplifier module, and a detector module. 3. [Oscillograph: Used to observe the input signal, intermediate signal, and output signal's wave forms, and assist in circuit tuning.] 4. Signal generator: provides input test signals of different frequencies and amplitude. 5. Power supply: provides a stable supply voltage for the entire spectrum circuit. 6. Other auxiliary components, such as resistance, capacity, induction, etc., were used for circuit connection and signal matching. ** 4. Experimental Steps ** 1. ** Circuit Connection ** - According to the circuit diagram, connect each circuit module to the single-chip development board. First, connect the power circuit to ensure that each module is supplied with the appropriate power supply voltage. - Connecting the input and output ports of the program control decay module, connecting the input signal to the program control decay module, and connecting the decayed signal to the filtering module, the frequency mixing module, the fixed gain amplifying module, and the detection module in turn. - The output of the detector module was connected to the ADC pin of the single-chip computer so that the single-chip computer could collect the detected direct current signal. - It is connected to the phase-locked loop chip to provide the local oscillation signal for the mixing module. - The I/O interface of the single-chip computer was used to connect the control signal to the control pins of each circuit module, such as the control pin of the program controlled decay module, the control pin of the phase-locked loop chip, etc. 2. ** Single-chip programming ** - Initialize the system clock, ADC, timer, and other internal resources of the single-chip computer. - Write a program to realize the control logic of the program control decay module, phase-locked loop chip, etc. For example, through the I/O port of the single-chip computer to output control signals, set the decay value of the program controlled decay module, the output frequency of the phase-locked loop chip, and so on. - Write the ADC acquisition program, and set the ADC's parameters such as the frequency and resolution to collect the detected direct current signal. - Realizing the spectrum analysis algorithm. A Fast FT Transform (FFT) algorithm can be used to convert the collected time domain signal into a frequency domain signal to obtain the frequency spectrum information of the signal. - Write a display program to display the spectrum information in a suitable way. For example, a LCD screen could be used to display information such as frequency and spectrum. 3. ** Circuit Testing ** - Observe the input signal's wave form with an earpiece and check whether the frequency and amplitude of the signal meet the design requirements. - After the circuit connection was completed, he gradually powered up each circuit module and observed the output signal wave of each module. For example, observe the filtering effect of the output signal of the filtering module, whether the intermediate frequency signal output by the mixing module is correct, and so on. - To ensure the accuracy of the program, the program could be debugged using a serial port or other means to check the variable values and program execution process during the program operation. - He adjusted the parameters such as the decay value of the programmed decay module and the output frequency of the phase-locked loop chip, observed the changes in the frequency spectrum results, and optimized the performance of the circuit and program. ** 5. Experimental results and analysis ** 1. ** Spectral result displayed ** - Through the LCD screen or other display devices, the frequency spectrum of the input signal was successfully displayed. The frequency spectrum could clearly reflect the frequency components of the signal and its magnitude relationship. For example, for an input signal synthesized by multiple sinewaves of different frequencies, the frequency spectrum could accurately display the frequency peak and the magnitude of each sinewave. 2. ** Accuracy of frequency measurement ** - The accuracy of the measurement of the frequency of the signal by the frequency spectrum circuit was measured by comparing it with the known frequency signal output by the signal generator. The experimental results showed that within a certain frequency range, the spectrum circuit could accurately measure the frequency of the signal, and the error was within an acceptable range (for example, the error was less than 5%). 3. ** Amplitude measurement accuracy ** - Comparing the input signal with a known amplitude, the accuracy of the signal amplitude measurement by the spectrum circuit was analyzed. Due to the influence of various noise and non-linear factors in the circuit, there may be some errors in the amplitude measurement. Through the analysis of the experimental data, it was found that the amplitude measurement error mainly came from the gain error of the programmed decay module, the amplifier module, and the non-linear detector module. ** 6. Experiment summary ** 1. This experiment successfully designed and implemented a frequency spectrum circuit based on a single-chip computer, which could analyze the input signal and display the spectrum results. 2. During the experiment, problems such as circuit connection errors, single-chip program logic errors, signal interference, etc. were encountered. Through careful circuit inspection, program tuning, and some anti-interference measures (such as reasonable wires, adding filter magnets, etc.), these problems were finally solved. 3. The experimental results showed that the frequency measurement and the amplitude measurement were accurate, but there were also some sources of error. In the subsequent improvements, the performance of the spectrum circuit could be improved by selecting higher-precision circuit modules and optimization algorithms. 4. Through this experiment, the core control function of the single-chip computer in the spectrum circuit and the basic principle and implementation method of the spectrum analysis were deeply understood, which laid the foundation for the further development of related electronic circuit design and research. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
