5.9 Frequency Response of the Common-Emitter Amp
www.ittc.ku.edu“implies” that the impulse response of the amplifier is: gt( )=−200δ(t) Are you saying the impulse response of the common-emitter example is not this function? A: It is definitely not that function. The impulse response gt( )=−200δ(t) is ideal—the impulse response of an amplifier with an infinite bandwidth!
