摘要
The frequency converters have first mixers for frequency converting input intermediate frequency band television signals into first intermediate frequency band television signals, first local oscillators for inputting the first local oscillation signals into the first mixers, second mixers for frequency converting the first intermediate frequency band television signals into the broadcasting channel television signals, and second local oscillators for inputting second local oscillation signals into the second mixers, wherein the frequency of the first local oscillation signals in the first frequency converter and the frequency of the first local oscillation signals in the second frequency converter are different from each other by 0.25 MHz or more.
