Abstract
A falling-edge modulation signal receiver is configured to process an input signal having a duty cycle varying with a bit value of the input signal. The receiver includes: a phase-locked loop for generating an oversampling clock according to the input signal which correlates with a signal clock, wherein the oversampling frequency is not lower than five times the frequency of the signal clock; an oversampling circuit for sampling the input signal according to the oversampling clock and thereby generating multiple groups of data which as a whole is corresponding to a single bit of the input signal; and a decision circuit for ascertaining that X bits of the multiple groups of data are 1 and determining the value of the single bit according to the X. When the X is greater/less than a threshold, the decision circuit determines that the value of the single bit is 1/0.
