Unformatted text preview: f systems S1
and S2 as shown in Fig. P2.21(a).
Denote the output of S1 as:
Denoting the output of S2 as y[k] (given that the input is w[k]):
Substituting the first equation into the second one we’ll have:
(iii) Calculate the input-output relationship for the parallel configuration of systems S1
and S2 as shown in Fig. P2.21(b).
The outputs of systems in parallel are added:
(iv) Show that the series and parallel configurations of systems D1 and S2 are LTI
Since both represent linear, constant coefficient differential equations then both systems
are LTI systems....
