A television signal transmitter is arranged by a first frequency converter for up-converting an input signal into an intermediate frequency signal, and a second frequency converter for down-converting the intermediate frequency signal into a television signal of any of channels within a predetermined output frequency band. In this television transmitter, a picture intermediate frequency of the intermediate frequency signal is set to be higher than a maximum frequency of the output frequency band, and is set to be lower than a doubled picture frequency of any one of the channels within the output frequency band by 1.25 MHz.
