302.~ Input signal combined with local oscillator or carrier frequency signal

DEFINITION

Classification: 329/302

Input signal combined with local oscillator or carrier frequency signal:

(under subclass 300) Subject matter where the modulated signal input to the demodulator interacts with oscillations from a secondary source.

(1) Note. The secondary oscillations may be internally generated or externally supplied and may be at a frequency other than that of the modulated input signal's carrier.
