1.8 STANDARD DISCRETE TIME SIGNALS

The standard discrete time signals are discrete time sinusoids, unit sample sequence, unit step signal, unit ramp signal and exponential signal etc. which are very useful in the analysis of discrete time systems. Let us represent the other standard signals.

1.8.1 Unit Sample Sequence

The unit sample sequence δ(n) which is very similar to the unit impulse signal δ(t) can be represented mathematically as follows:

We can write it in the sequence form as follows:
