Clock pulse generating system for telecommunications - uses separate frequency dividing counters for each train of clock pulses

摘要

The clock pulse generating system, for telecommunications equipment, uses a separate counter for each train of clock pulses. The fundamental clock pulses are passed to each counter which acts as a frequency divider. The output pulses from the counters are passed to circuits that mark the clock pulses and to reset the counters. For safety, two synchronised counters are employed for each train of clock pulses.
