Abstract

Apparatus for demodulating a train of pulses includes a one-shot device having an asynchronous data input terminal, which is configured to receive the train of pulses, and a one-shot data output terminal. A first clocked logic gate has a first clocked data input terminal, which is coupled to the one-shot data output terminal, and a first clocked data output terminal. A combinatorial logic gate has combinatorial input terminals, which are coupled to the one-shot and first clocked data output terminals, and a combinatorial output terminal. A second clocked logic gate has a second clocked data input terminal, which is coupled to the combinatorial output terminal, and a second clocked data output terminal, which is configured to output a demodulated envelope of the train of pulses.
