Reduction Of Interchannel Harmonic Distortions In An Analog And Digital Signal Multiplex
US Patent:
5450392, Sep 12, 1995
Filed:
May 1, 1992
Appl. No.:
7/877824
Inventors:
Joseph B. Waltrich - Glenside PA
Assignee:
General Instrument Corporation - Hatboro PA
International Classification:
H04H 104, H04J 112
US Classification:
370 6
Abstract:
A frequency allocation is provided to minimize the effects of amplifier distortion in a mixed analog and digital cable television system. In particular, successive digital channel signals having a bandwidth substantially equal to. omega. are separated by a pair of adjacent analog channel signals, each having a bandwidth substantially equal to. omega. In an illustrated embodiment, the analog and digital channel signals comprise amplitude modulated carriers having substantially equal power levels.
