Is this system Time-varying?

    Hi.

    there is a system.

    y[n]=x[n^2]

    is this system time varying?

    I think it is.

    to show time invariant.

    delay -> system = system -> delay

    so.

    1. delay -> x[n-n0] -> system = x[ n^2 - n0 ]

    2. system -> x[ n^2 ] -> delay -> x[ (n-n0)^2 ]

    which are not same. so It is time varying.

    AM I RIGHT?
