AFC Interface circuit |
摘要 |
An interface circuit that couples the output of a differential AFC detector to a tuner and in so doing provides a single-ended control signal and a substantially constant reference signal. A bridging circuit combines the differential outputs to effect a substantially constant signal which is appropriately scaled by a referencing circuit so as to develop the reference voltage required. A dividing circuit coupled to one of the differential outputs develops an AFC control voltage having the range required to accommodate the tuner's AFC-responsive circuitry.
