Class Information
Number: 455/130
Name: Telecommunications > Receiver or analog modulated signal frequency converter
Description: Apparatus comprising (a) means for receiving a carrier wave, upon which an information signal has been modulated, and deriving the original information signal from the modulated carrier wave. Further means may be provided for converting the derived signal into a physical manifestation readily perceived by at least one of the human senses (e.g., sound) or (b) devices whereby an incoming carrier wave signal, which has been modulated by an analog signal, is changed from one carrier frequency to another carrier frequency.
