DIGITAL ADAPTIVE-TO-LINEAR DELTA MODULATED SIGNAL CONVERTER

A digital adaptive delta modulated (ADM) to linear delta modulated (LDM) signal converter is disclosed which operates at a predetermined multiple, m, of the applied adaptive modulated signal bit rate, 1/T. At each pulse time of the ADM signal, the adaptive step size is determined in a conventional m...

More Information
Summary:A digital adaptive delta modulated (ADM) to linear delta modulated (LDM) signal converter is disclosed which operates at a predetermined multiple, m, of the applied adaptive modulated signal bit rate, 1/T. At each pulse time of the ADM signal, the adaptive step size is determined in a conventional manner; the determined step size is then utilized to develop a signal which is a linear delta modulated representation of the applied ADM signal.
