Quantization error occurs in ________(a) Time Division Multiplexing(b) Frequency Division Multiplexing(c) Pulse Code Modulation(d) Pulse Width ModulationThis question was addressed to me during a job interview.This intriguing question comes from Methods of Reducing Distortion in chapter Amplitude Modulation of Analog Communications

Answer»

The correct answer is (C) Pulse Code Modulation

Explanation: The difference between an input VALUE and its quantized value is called quantization error or we can also see it as that when an ANALOG number is not CONVERTED into an exact digital number. It takes place in pulse code modulation (PCM). Pulse Code Modulation is a TECHNIQUE in which the amplitude of an analog signal is converted to a binary value represented as a series of pulses.
