DEFINITION

Classification: 455/295

Modulation distortion or cross talk correction or elimination:

(under subclass 130) 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.

(1) Note. Some examples of the various sources of distortion are selective fading, attenuation in the transmitting medium, cross-talk, etc.
