Question

Waveform coders has _______ complexity and achieves _______ economy in transmission bit rate.

(a) Maximum, moderate

(b) Maximum, high

(c) Minimal, moderate

(d) Minimal, high

I have been asked this question in a job interview.

I would like to ask this question from Characteristics of Speech Signals in chapter Speech Coding of Wireless/Mobile

Answer 1

Correct choice is (c) Minimal, moderate

For explanation I would say: Waveform coders have minimal complexity. This class of coders achieves only moderate economy in transmission bit rate. They are designed to be source independent and hence code equally well a variety of signals.
