Abstract :
A time encoding machine is a real-time asynchronous mechanism for encoding amplitude information into a time sequence. We investigate the operating characteristics of a machine consisting of a feedback loop containing an adder, a linear filter and a Schmitt trigger. We show how to recover, loss-free, the amplitude information of a bandlimited signal from the time sequence.
