DEFINITION

Classification: 455/85

Transmitter oscillator used as detector:

(under subclass 84) Subject matter wherein the active element circuitry which produces the carrier signal during transmission functions as a demodulator during signal reception.

(1) Note. The term demodulator used above excludes heterodyning mixers. Rather it includes only those devices producing a signal which is a replica of the original modulating information signal.
