Abstract
PURPOSE:To avoid a disturbance frequency, and to use a television using a tuner of a small size and low power accordingly by constituting a transmission channel of a group of specific television channels, and setting an intermediate frequency of a television receiver to 58MHz band. CONSTITUTION:In case the transmission channel is constituted of A-5, A-3, 7, 11 and 13 of American channels, or American channels A-5, A-3, 8, 10 and 12, and a Japanese channel 12, when an IF frequency is selected to 58MHz (58.75MHz video intermediate frequency), the group of transmission channels is all not in a relation of adjacent channels, therefore, an adjacent channel disturbance is not generated. An image disturbance frequency of a TV unit does not coincide with any transmission signal frequency, therefore, an image disturbance is not generated either. Therefore, a design for miniaturizing a tuner can be executed easily.
