Shown in figure below is a system in which
the input signal is multiplied by a periodic square wave.
The period of s (t) is T. The input signal is band limited
with | X(jw) |=0 for |w|>wm .
(a) For
determine, in terms of wm , the maximum value
of T for which there is no aliasing among the
replicas of X (jw) in W(jw).
(b) For
determine, in terms of wm , the maximum value
of T for which there is no aliasing among the
replicas of X ( jw ) in W( jw ).
determine, in terms of wm , the maximum value
of T for which there is no aliasing among the
replicas of X (jw) in W(jw).
determine, in terms of wm , the maximum value
of T for which there is no aliasing among the
replicas of X ( jw ) in W( jw ).
