By varying the weight of the coefficients and the number of filter taps, virtually any frequency response characteristic can be realized with an FIR filter. As has been shown, FIR filters can achieve performance

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!

people.ee.duke.eduAdditionally, an ideal filter must have an impulse response that extends to infinite time before and after the pulse peak and, if the filter is to be causal (output response occurs after the input is applied), the peak output would occur an infinite time after the input. This would
