THE RATING OF DELTA SIGMA MODULATING SYSTEMS, WITH CONSTANT ERRORS, BURST ERRORS AND TANDEM LINKS IN A FREE CONVERSATION TEST USING THE REFERENCE SPEECH LINK

Abstract

The report describes a free conversation opinion test, designed on a statistical basis, to assess the performance of Delta Sigma equipments, connected both singly and in tandem. Tests were made at digit rates of 19/2 kb/s and 12 kb/s. The single links were tested with errors introduced into the digit stream, the errors being either randomly distributed at a constant density of 10% or in bursts. In all cases the Delta Sigma equipments were rated higher on the sensitivity/noise scale than the Army Standard.
