Abstract
A high speed counter circuit for counting electrical pulses includes a master/slave flip-flop at the input stage of the counter. An AND gate logically ANDs the pulses being counted with the master output to produce a first gating signal. A plurality of cascade coupled flip-flops each having a slave and an inverse slave output are provided. The clock input to each cascade coupled flip-flop is produced by the logical OR of the electrical pulses being counted, the first gating signal and the slave output of all preceding flip-flops of the counter. The counter output is provided by the inverse slave output of each flip-flop.
