Models for Intersample Response
Most of the book deals with sampled models that describe the signals at the sampling instants. In this chapter we focus on describing the system response that occurs between samples. The ideas presented here build on the results for the at-sample response previously presented in the book. Two views of the intersample response are presented, namely in the frequency domain and the time domain.
Intersample response can be modelled using modified Z-transforms
The frequency-domain ideas described in Sect. 21.1 are explained in greater detail in
