ABSTRACT:
In a CATV converter system which converts any of a number of input frequencies to the frequency of a predetermined channel, the converter is bypassed when the input signal selected is of the same frequency as the predetermined channel. Instead of going into the converter the input signal is sent through a filter circuit into the associated circuits, thereby avoiding the generation of a beat frequency that would arise unless the converter frequency were precisely matched to the predetermined channel frequency.
