Abstract
A circuit arrangement for combining a temperature compensating signal from a temperature compensator with a modulation signal to provide a combined signal for driving one or more crystal oscillators independently. The combining is carried out in such a manner that there is a constant predetermined ratio between the magnitudes of the temperature compensating and modulating signals. A potentiometer level controls the combined signal to each oscillator independently without changing the predetermined ratio. Thus, the effect of circuit element tolerances on temperature compensation is automatically corrected for while the central oscillation frequency in the absence of modulation is substantially unaffected.
