1. 对于电压串联负反馈: - 根据定义:开环增益\(X_{o}/X_{i}' = U_{o}/U_{i}'\)(很大),闭环增益\(A_{uuf}=U_{o}/U_{i}=A_{uu}/(1 + F_{u}A_{uu})\)。 - 在深度负反馈情况下,闭环放大倍数的估算公式\(\dot{A}_{f}\approx1/\dot{F}\)或\(\dot{X}_{i}\approx\dot{X}_{f}\)。 2. 对于电压并联负反馈: - 根据定义开环增益\(A_{ui}=X_{o}/X_{i}' = U_{o}/I_{i}'\)(很大,有量纲,量纲是电阻,放大倍数广义化)。 - 反馈系数\(F_{iu}=X_{f}/X_{o}=I_{f}/U_{o}=- 1/R_{f}\)(有量纲,量纲是电导)。 - 闭环系统时将负反馈直接算作系统的一部分,系统的输出为\(X_{o}\),输入为\(X_{i}\),自然放大倍数为输出比输入。开环系统时,只考虑系统的开环部分,可直接将反馈支路去掉,实际上\(X_{i}=X_{i}'\),系统放大倍数也是输出比输入为\(X_{o}/X_{i}\)。求一个系统的放大倍数无需看系统的内部,只需看系统外部的输出与输入幅值之比就可以。 点击前往免费阅读更多精彩小说

Reaction Formula of CaSO4 and CaCO3

The chemical equation of the reaction between calcium sulfuric acid (CaSO) and sulfuric acid (H ^CO) is: CaSO + H ^CO = CaCO + H ^SO. This was a metathesis reaction. During the reaction, the sulfuric acid ions (SO2) exchanged positions with the carbon dioxide ions (CO2) to form calcium carbonite and sulfuric acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What are some interesting closed time travel loop stories?

One well - known closed time travel loop story is 'Groundhog Day'. Bill Murray's character relives the same day over and over. It's like a time loop where his actions in each iteration gradually change him and the events around him. Another is in the movie 'Predestination' which has a complex time - traveling plot where the main character is involved in a self - perpetuating cycle of events that span across different times in their life.

Closed Circuit Based on True Story: What are the real - life events that inspired it?

I'm not entirely sure about the specific real - life events that inspired 'Closed Circuit'. It could be related to legal cases involving secrecy, security, and the balance between justice and national security. Maybe it was drawn from cases where there were issues with classified information in a courtroom setting.

How do closed time travel loop stories challenge our understanding of time?

Closed time travel loop stories challenge our understanding of time by messing with causality. Normally, we think of cause and effect in a linear way. But in these stories, an effect can be its own cause. For example, if a character goes back in time to give their past self an idea that leads to them inventing time travel in the future so they can go back in time to give that idea. It makes you question the very order of how things happen in time.
