ASYNCHRONOUS PULSE MODULATION FOR THRESHOLD-BASED SIGNAL CODING

摘要

A method of signal processing includes comparing an input signal with one or more positive threshold values and one or more negative threshold values. The method also includes generating an output signal based on the comparison of the input signal with the positive threshold(s) and negative threshold(s). The method further includes feeding the output signal back into a decaying reconstruction filter to create a reconstructed signal and combining the reconstructed signal with the input signal.
