Peak Signal-to-Noise Formulas for Multistage Delta Modulation with RC-Shaped Gaussian Input Signals

Delta modulation (DM) has been extensively studied,1_H and following its integration onto a chip,9 it is being increasingly used in industrial applications. The salient advantages of DM are robustness to transmission errors; tolerance to clock jitter; simple filtering requirements; suitability for encryption; and low complexity resulting in inexpensive implementation. In typical applications, the ratio fp/fc is
