Fii why the amplification circuit, feedback coefficient is the ratio of the resistance

Pretty good, I feel the causes of the current

CodePudding user response:

If the us=uo is like this

Can't send pictures, also don't know you can add me WeChat, 395233700

CodePudding user response:

First review the analog circuit, and then look at this problem, as simple a lot of,

CodePudding user response:

You need to have a look at the model, the equivalent model of single tube amplifier circuit to understand, in this two words also said not clearly,

CodePudding user response:

This figure backwards,,, haven't taken full, conditions of all don't know, when you really do after the product or development board, putting yourself, will be easy to understand,
