Abstract:
A method for generating pulses from analog waveforms comprising:exciting, with a known but arbitrary analog waveform, a circuit with a variable operating point and having a transfer function characterized by an unstable operating region bounded by a first stable operating region and a second stable operating region, wherein said analog waveform has a first information region and a second information region;responsive to sensing of said first information region, forcing said variable operating point to vary in order to initiate operation of said circuit in said unstable operating region to produce at least one oscillation, said oscillation having a frequency greater than the rate of change of said operating point; andresponsive to sensing of said second information region, forcing said variable operating point to vary into either one of said stable operating regions in order to terminate said at least one oscillation without transients;wherein said initiating and said terminating alternate.
