Given a bandlimited signal x(t)=sinc (t/4) cos (2?t) form a signal x [n] by sampling x(t) at a rate fs=4 and form an information-equivalent impulse signal 
by multiplying by a periodic sequence of unit impulses whose fundamental frequency is the same 
. Graph the magnitude of the DTFT of and the CTFT of . Change the sampling rate to and repeat.
