An Investigation of Quantization Noise

Authors: Blesser, Barry A.

AES Convention 46 · Paper 929 · September 1973

Abstract

Because a digital system contains a fixed number of discrete levels, there will be a difference between the digital representation and the analog signal. The subjective consequences of this quantization error is a function of the program. For complex high-level program it is white noise; for complex low-level program, it is a kind of distortion. With sine waves an extraneous set of beat tones will be generated. For example, a 9.33 kHz input signal with a 30 kHz sampling system wil generate a 2 kHz beat tone.
