Consider an open loop system having a transfer function G(s) = (s + 4)–1 and a sampler placed before G(s). Find its output c(t) by the conventional z-transform analysis for a sampling period h = 1 s with a unit step input. Also, determine the output of the system via
δ-domain DOTF approach. Consider m = 10 and T = 10 s.
Compare the results obtained by two methods of analysis by estimating the percentage errors.
