WebOne test to verify time invariance/variance property of a system is to shift the response of the system to an input signal and apply a shifted input, to the same system and compare the two waveforms, so obtained. If the system is time invariant, the two waveforms will match when the input and output shifts match.

WebJan 13, 2024 Β· To be time invariant you would have to show that: $$y(n-k) = (n-1)x(n-k-1) + (n+1)x(n-k+1)$$ (You shift the $x$ and you get a shift in $y$).
