ABSTRACT:
An output circuit for converting a video signal reproduced from a video signal reproducing apparatus such as a video tape recorder, to a signal in the form of an RF signal in terms of a television channel carrier and selectively producing one of two channel carriers, comprises a first filter for eliminating the lower sideband wave of the lower one of the two channels, a second filter connected in series with the first filter for eliminating the lower sideband wave of the higher one of the two channels, and a switch for activating the second filter only when the higher channel is selected to produce the higher channel signal.
