Convention Paper

The Subjective Effect and Measurement of A.D.C./D.A.C. Transfer Characteristic Discontinuity

Authors: Gilchrist, Neil H.

AES Convention 81 · Paper 2394 · November 1986

Abstract

Differential linearity error in audio analog/digital converters can produce discontinuities in the transfer characteristics, with consequent audible impairment of the signal. Subjective tests have been conducted to determine the impairment caused, and results are given in the paper. Conventional analog distortion measurement methods are insensitive to the distortion products caused by discontinuities and can be difficult to interpret. A computer-based measurement technique is described which is sensitive to these distortion products, and indicates the size of a discontinuity and its approximate position in the transfer characteristic.
