    Digital System

    Hi, I am wondering if anyone could help me with this please. I am not sure which properties the following digital system displays

    Question: Which of the following properties are exhibited by the digital system represented by

    h[n] = r [4-n]u[n]?

    Linearity, time- variance, causality stability and memory.

    NB: r[n] is the ramp function and u[n] is the step function.


    I am not sure how to work it out. sorry and thanks

    first thing to do is ensure you know what all those terms mean.

    once you do determining which of those properties $h[n]$ has is pretty simple.
