H03J7/08 - CPC Classification

Classification description:

Automatic frequency control; Automatic scanning over a band of frequencies; Automatic frequency control 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

Sub-classes:

H03J7/10 » Modification of automatic frequency control sensitivity or linearising automatic frequency control operation 8
H03J7/12 » Combination of automatic frequency control voltage with stabilised varactor supply voltage 3
