ABSTRACT:
A maximum frequency detector having a counter which counts through a certain number of counts unless an inhibit signal is received at a rate determined by the frequency of the clock pulse received. The inhibit signal is generated by a logic network to prevent the counter from producing an outgoing digital pulse of the digital pulse stream. The counter, the clock pulse generator and the logic network cooperate to have the frequencies of the incoming and outgoing digital pulses equal unless the incoming digital pulse stream has its frequency exceed the predetermined maximum frequency. In the event that the frequency of the incoming digital pulse stream exceeds the predetermined maximum frequency the frequency of the outgoing digital pulse stream is the certain predetermined maximum frequency.
