Question

Is discrete time convolution possible?

(a) True

(b) False

The question was asked during an interview for a job.

I need to ask this question from Discrete Time Convolution topic in chapter Time-Domain Analysis of CT Systems of Signals and Systems

Answer 1

Correct option is (a) True

To explain I would say: Yes, like continuous time convolution discrete time convolution is also possible with the same phenomena except that it is discrete and superimposition occurs only in those time interval in which signal is present.
