Beschreibung
Zusammenfassung:	FIELD: physics. ^ SUBSTANCE: device consists of a bias voltage generator (9), the input of which is connected to the output of the control unit (8), and the output of which is connected to an avalanche photodiode (11), and a comparator (12). The control unit has extra elements for controlling bias voltage, operation threshold and time for switching on and off comparator (12) of photoelectric pulses. The output of elements for controlling operation threshold and on and off switching time is connected to the inputs of comparator (12), and the output of comparator (12) is connected to the input of the generator (14) of output pulses. ^ EFFECT: complete or partial suppression of undesired electrical pulses. ^ 2 dwg
