Abstract
A digital frequency-lock circuit has a binary rate multiplier connected between a fixed frequency oscillator and an output terminal to modify the oscillator output signal in accordance with a digital word. An up/down counter is arranged to supply the digital word to the rate multiplier in accordance with a count stored in the counter. The frequency of the rate multiplier output is compared with an input signal frequency during a cycle of the input signal to maintain a predetermined relationship between the compared frequencies.
