Combination of automatic frequency control voltage with stabilised varactor supply voltage

Full Title

Automatic frequency control; Automatic scanning over a band of frequencies > Automatic frequency control (H03J7/18 takes precedence) > where the frequency control is accomplished by varying the electrical characteristics of a non-mechanically adjustable element or where the nature of the frequency controlling element is not significant > using varactors, i.e. voltage variable reactive diodes (H03J7/06 takes precedence) > Combination of automatic frequency control voltage with stabilised varactor supply voltage
