(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Prove that the system is either T.I. or is not T.I.

2. Relevant equations

y(n) = x(n)*h(n)

x(n) is the input signal

y(n) is the output signal

h(n) is the system

3. The attempt at a solution

Inputing x(n-n0) into the system I get out:

as the output x(n-n0)*h(n)

Since y(n-n0) = x(n-n0)*h(n-n0) != x(n-n0)*h(n) the system is not T.I.

I think I am doing this wrong.
