Digital modulation
Digital modulation is carried by using a sinusoidal carrier modulated (shift Keying) by
using the information (message) which is digital. The Fig. below shows the ASK, FSK and

.To study the methods of generating PSK signals
Theory:In this method, the phase can only adopt two discrete values. The method is therefore
known as two phase shift keying

Solutions of Homework 1
1. By definition a signal is even if and only if x(t) = x(-t) or x[n] = x[-n], while a signal is odd if and
only if x(t) = -x(- t) or x[n] = -x[-n].
Since x(
