Asynchronous pulse modulation for threshold-based signal coding

摘要

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