Expert Solution

Step 1

“Since you have asked multiple question, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question.”

Discrete-time Fourier transform (DTFT) is a Fourier transformation method that works on numerical sequence.

DTFT is often used to analyze work activity samples. The term discrete-time refers to the fact that change is applied to direct data, usually sampling its interval with time units.
