9.~ Oscillator with distributed parameter-type discriminator

DEFINITION

Classification: 331/9

(under subclass 1) Subject matter wherein the A.F.S. control circuit of the oscillator is provided with a frequency sensing means of the distributed parameter type (e.g., cavity resonator).

SEE OR SEARCH THIS CLASS, SUBCLASS:

3, for A.F.S. systems utilizing a molecular resonance type discriminator.

25+, for A.F.S. systems wherein the discriminator is of the signal or phase comparing type having at least two inputs for the signals (of the controlled oscillator and reference source) to be compared.

32+, for A.F.S. systems having a single input type discriminator.
