Methods and apparatus for signal processing

摘要

A method and apparatus for signal processing may include an electronic circuit comprising a receiver configured to receive a signal and a dynamic threshold circuit configured to process the signal. The dynamic threshold circuit is configured to compare the signal to a threshold and generate an output signal according to the comparison. The dynamic threshold circuit is also configured to change the threshold to a selected level at a selected time. In various embodiments, the selected level is selected to be a level between the level of the input signal and a midpoint of the input signal. In another embodiment, the selected time is selected to correspond to a stabilization time of the input signal.
