Delta Modulation of Data Signals

This paper is an analytical study to determine the performance of single-integration delta-modulation
(\DeltaM)
encoders with inputs which are various voice-band data signals. Signal-to-quantizing noise ratios
S/N
are calculated for
\DeltaM
bit rates from 16 to 96 K bits/s. The input data signals studied are phase modulation at 1200 and 2400 bits/s, partial response at 4800 and 9600 bits/s, and single sideband at 4800 bits/s. Predictions of the performance of these modems, when transmitted over the
\DeltaM
systems, are based on the calculated
S/N
ratios.
