Abstract

See full text

A digital Binary Amplitude Shift Keying (BASK) demodulator and decoder and method of decoding encoded BASK modulated signals, where the method samples peak amplitude values of a processed version of a modulated signal to provide sampled values that are digitized to form digitized values. The digitized values are stored in a sequence order based on an order in which the peak amplitude values corresponding to the digitized values were sampled. The digitized values are filtered using their sequence order to provide filtered modulated digital signals. Transitions of the first filtered modulated digital signal are identified during a data bit duration and decoded demodulated binary data streams are then selectively generated.
