Why is the volume control of the amplifier reversed?The volume control of the amplifier was reversed. This was a little strange. Normally, the volume would be increased clockwise and decreased counterclockwise. If it was the opposite, it could be that the internal circuit of the amplifier was connected wrongly, or there was a problem with the settings. Some amps had special settings to adjust the direction of the volume control. It was also possible that the volume control was broken. In this case, professional maintenance personnel might be needed to check and repair it.

Is the feedback amplifier circuit a closed loop circuit?In an amplifier circuit, a circuit with feedback was called a closed-loop circuit. The feedback amplifier circuit had a feedback path from the output to the input. This feedback circuit was in a closed-loop state, so the feedback amplifier circuit was a closed-loop circuit.

Huawei mobile phone camera amplifier functionIf you want to use the magnifying function of the Huawei phone camera (similar to the magnifying function), you can do the following:
1. He turned on the phone's camera and entered the photo mode. He stretched the page with two fingers, and the camera page would automatically zoom. The greater the stretch of the two fingers, the higher the focus and the farther the zooming distance.
2. You could also adjust the focus by using the focus button on the right side of the camera. The further you pulled it up, the farther you zoomed in.
3. He clicked to take a picture and then clicked on the zoom factor on the right. 1 times was the normal size. More than 1 times would have the effect of a telescope (magnifying). The higher the zoom factor, the farther the distance could be seen. At present, Huawei's mobile phones could support up to 50 times zooming. In the settings, the process of turning off the zoom-in gesture was as follows: find the settings in the phone and click on it; after entering the settings, click on more settings; click on no obstacles; find the zoom-in gesture and click off after entering it.

Why is the common-emit amplifier circuit inverted?In the common-emitting amplifying circuit, when the input signal is positive for half a cycle, the base potential of the NPM triode is raised by the input signal, the base voltage to the ground increases, and the degree of continuity increases, that is, the resistance of the collector and the transmitter decreases, the current increases, the voltage at both ends of Rc increases, the voltage of the C pole of the triode to the ground decreases, and the output capacity enters a discharge state when the potential of the output is higher than that of the C pole. At this time, the lower end of the load Ri is positive, the upper end is negative, and the output signal is negative for half a cycle. When the input signal is in the negative half cycle, the base potential is pulled down by the input signal, the voltage of the B pole to the ground is reduced, the degree of continuity is reduced, the current is reduced, the voltage at both ends of Rc is reduced, the potential of the C pole is raised, and the output voltage is lower than that of the C pole. At this time, the lower end of the load Ri is negative, the upper end is positive, and the output signal is in the positive half cycle. Therefore, the input and output of the common-emit amplifier circuit were reversed.
