WebSep 15, 2024 · How to check whether a system is time invariant or time varying. Let y1(t) be the output corresponding to x1(t). Consider a second input x2(t) obtained by shifting x1(t) i.e x2(t) = x1(t-to) and find the output corresponding to the input x2(t). From the step 1, find y1(t-to) and compare with y2(t). If y2(t) = y1(t-to), then the system is time ...
