14.10 THE SYSTEM FUNCTION AND SIGNAL DISTORTION
We formally define the system function of a linear circuit below.
The system function for a particular input-output pair is the ratio of Fourier transform of the zero-state response of the output variable to Fourier transform of the input variable. It is the same as frequency response function defined for that input-output pair. It is numerically the same as Fourier transform of the impulse response for that input-output pair.
The system function of a circuit can be obtained by applying circuit analysis principles on the phasor equivalent circuit. The system function of a memoryless circuit will be a real number, independent of frequency. The system function of a lumped linear time-invariant dynamic ...
