Abstract
PURPOSE: To increase the transmission quality with lower clock frequency, by obtaining the difference between the input analog signal and the analog signal delayed for a given time and by comparing the output of the local decoder with the difference, in the delta modulating circuit modulating the analog signal into digital signal.
