Differential amplitude discriminator with digital/analog control

Abstract

A differential amplitude discriminator is described that can operate both with a constant threshold of discrimination (registration of the number of pulses over sequential time intervals), and in the amplitude analysis mode, when discrimination levels change automatically by the chosen value ΔU. This circuit can be applied when locking the output signals to the time of arrival of the input pulses is not required. © 1996 MAHK Hayka/Interperiodica Publishing.
