发明名称 REDUCTION OF INTERCHANNEL HARMONIC DISTORTIONS IN A ANALOG AND DIGITAL SIGNAL MULTIPLEX
摘要 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. <IMAGE>
