Question

We need not relate the spectrum of y(m) to spectrum of x(n) to obtain frequency response characteristic of y(m).

(a) True

(b) False

The question was asked in semester exam.

The origin of the question is Decimation by a Factor D in chapter Multirate Digital Signal Procesing of Digital Signal Processing

Answer 1

Correct option is (b) False

For explanation I would say: The frequency domain characteristic of the output sequence y(m) can be obtained by relating the spectrum of y(m) to the spectrum of the input sequence x(n).
