Question

Quantization is a process of mapping a ________ range of amplitude of a signal into a finite set of __________ amplitudes.

(a) Continuous, discrete

(b) Discrete, continuous

(c) Discrete, discrete

(d) Continuous, continuous

I had been asked this question in semester exam.

The origin of the question is Quantization Techniques in section Speech Coding of Wireless/Mobile

Answer 1

The correct choice is (a) Continuous, discrete

Easiest explanation: Quantization is a process of mapping a continuous range of amplitude of a signal into a finite set of discrete amplitudes. Quantizers are the devices that remove the irrelevancies in the signal.
