Peak signal-to-noise ratio formulas for multi-stage delta modulation with RC-shaped Gaussian input signals
Peak signal-to-noise ratio formulas for multi-stage delta modulation with RC-shaped Gaussian input signals
A multistage delta modulation (MSDM) encoder contains a number of delta modulation (DM) stages, where each delta modulator encodes the band‐limited error of the previous delta modulator. The DM binary outputs are then multiplexed for transmission. By this technique, substantial gains in s/n compared to a single‐stage DM can be achieved at high transmitted bit rate to message bandwidth ratios (fp/fc). For Gaussian input signals having band‐limited resistance‐capacitance (rc) spectra, the peak s/n performance of MSDM as a function of (fp/fc) and the number of DM stages is presented. It is shown that like PCM, MSDM exchanges s/n with (fp/fc) on an exponential basis.

Abstract
A multistage delta modulation (MSDM) encoder contains a number of delta modulation (DM) stages, where each delta modulator encodes the band‐limited error of the previous delta modulator. The DM binary outputs are then multiplexed for transmission. By this technique, substantial gains in s/n compared to a single‐stage DM can be achieved at high transmitted bit rate to message bandwidth ratios (fp/fc). For Gaussian input signals having band‐limited resistance‐capacitance (rc) spectra, the peak s/n performance of MSDM as a function of (fp/fc) and the number of DM stages is presented. It is shown that like PCM, MSDM exchanges s/n with (fp/fc) on an exponential basis.
