Curriculum design, save the children, we do questions when simple frequency characteristic test instrument, the difficulties, amplifier and filter together, waveform, there is no change ah, don't know how to return a responsibility, all make for a long time,

CodePudding user response:

Is a simulation or measurement?

CodePudding user response:

Is course design of circuit test!

CodePudding user response:

What type of filter, high pass low pass band? Passband cutoff belt?

CodePudding user response:

Is the multiplier and fourth-order low-pass filter together in a row, waveform didn't have to change

CodePudding user response:

Don't understand the specific needs
