Frequency control system |
摘要 |
A circuit for producing a frequency dependent output signal in response to two a.c. input signals, including a converter unit connected to receive the two a.c. input signals for furnishing an output signal having a d.c. component which varies in dependence on changes in the value of a relationship between the frequencies of the two a.c. input signals, and a frequency generator connected to the converter unit for producing an a.c. output signal whose frequency is a function of the value of such d.c. component.
