in this case the value of signal is specified only at specified only at specific time....
so the signal represented at discrete interval of time is called as the discrete time signal....
the discrete time signal is generated from continuous time signal by using the sampling operation ........
characteristics of discrete time signal:-
1.discrete time sinusoidal signals are identical when there frequencies are separated by integer multiple of 2pi...
2.if the frequency of discrete time sinusoidal is a rational number ,then such signal is periodic in nature.....
3.for the discrete time sinusoidal,the highest oscillation is obtained when angular frequency w=+-pi....
