Hi. I have the following assignment, but I can't figure out how to plot it in matlab.
A linear time-invariant filter is described by the difference equation y[n] = x[n] - x[n-2]. Obtain an expression for the frequency response of this system: H(e^(j*w)=1-e^((-2)*j*w).
Sketch the frequency respons (magnitude and phase) as a function of frequency. - I would like to do this in matlab. Is it possible?

you could get familiar with the wintool and wvtool gui's. I think these tools are really straight forward. Good luck!
