Discriminator for disturbance signals - is fitted with pulse source, comparator and counter and has logic gate interconnections to counter

摘要

The disturbance signal discriminator is used in particular for an optical-electronic detector. The discriminator has a clock pulse source (CK), a comparator (P1) and a counter (R). The clock pulse source controls the detector (De) in synchronism with the comparator. A signal (F) registers the null setting of the counter for the detector to be connected with the counter input (H) through a logic gate (P2) which further has the inverse of the output signal (S) of a counter output (D). The signal formed with a detected object has a different logic condition form that formed by a disturbance signal.
