Question

________ is a delayed decision coding technique.

(a) Adaptive quantization

(b) Uniform quantization

(c) Vector quantization

(d) Non-uniform quantization

I had been asked this question by my school teacher while I was bunking the class.

This question is from Quantization Techniques topic in portion Speech Coding of Wireless/Mobile

Answer 1

The correct answer is (c) Vector quantization

Easiest explanation: Vector (VQ) quantization is a delayed decision coding technique. It maps a group of input samples called a vector to a code book index. A code book is set up consisting of a finite set of vectors covering the entire anticipated range of values.
