A Video Pulse Counter

reportActive / Technical Report | Accesssion Number: AD1214378 | Open PDF

Abstract:

As part of an investigation of the operation of a number of pulse sources on the same channel, a pulse counter has been designed which counts discrete video pulses. The maximum counting rate is two megacycles; the minimum counting rate is 25 cps. Each of six cascaded decade counter stages operates by storing pulse counts as capacitor charges. The counter operates for a crystal-controlled one-second interval, presenting the count it obtains on six panel meters. Each meter is calibrated from 0 to 9, there being one meter for each digit of the count.
