Abstract :
A technique is described to stabilise the operating point of a tunnel-diode threshold detector, permitting pulses of 5 mV amplitude and 200 ps duration to be detected reliably over a wide temperature range. The principle is to induce a known constant false-alarm rate in the detector, due to noise, and then use the aggregation of a sequence of hits to indicate a true signal.
