Class Information
Number: 455/295
Name: Telecommunications > Receiver or analog modulated signal frequency converter > Modulation distortion or cross talk correction or elimination
Description: Subject matter including means whereby intermodulation components occurring in a desired modulated carrier wave input signal, due to cross-modulation of the desired carrier by an undesired signal wave, are corrected for or whereby distortions of a desired modulated carrier wave input signal, which are due to causes other than interference external to the receiver system, are corrected for or eliminated.
