Phase comparator is combined with divider and digital feed. back loop to give highly accurate frequency multiplication over wide band of inputs. Multiplying factor is 1,000, but technique is adaptable to other values. Amplified output of phase comparator is used to regulate voltage-controlled oscillator.-W. O. Brooks, Stepping up Frequency with Counter Circuits, Electronics, 32:29, p 60-62.
