Digital receiver and method for demodulating pulse-width modulated signals
The present invention provides a digital receiver configured to demodulate or decode a pulse-width modulated (PWM) signal from a transmitter. The receiver digitally demodulates or decodes the pulse-width modulated signal so as to obtain (binary) values of data modulated on pulse periods of the pulse-width modulated signal. The digital receiver includes multiple delay cells coupled to one another in series and a sampling circuit coupled to one of the delay cells. A sequential coupling of the delay cells composes a signal path, and each of the delay cells is designed to provide a corresponding delay to a corresponding input signal propagating along the signal path so as to generate a delayed signal as its output.
