(b) p(mD)

(c) v(mD).p(mD)

(d) none of the mentioned

The question was posed to me during an interview for a job.

I'd like to ask this question from Decimation by a Factor D topic in portion Multirate Digital Signal Procesing of Digital Signal Processing

Answer 1

Right option is (c) v(mD).p(mD)

The explanation is: We know that the equation for y(m) is given as

y(m)= \(\bar{v}(mD)\)= v(mD).p(mD).
