Abstract: PURPOSE: A tuner is provided to locate a single tuner in a large-size apartment house to allow people dwelling in the apartment house to share the tuner. CONSTITUTION: A tuner(1) includes an input port(200), a band pass filter(300) and a fixed channel filtering unit(100). The fixed channel filtering unit has filters(102a,102b,102n) as many as the number of broadcasting channels. The broadcasting channels correspond to the filters one to one. Each of the filters passes only a single broadcasting channel signal. A voltage controlled oscillator(103a) transmits a predetermined frequency signal to a mixer(101a) such that a signal corresponding to a channel '1' among the output signals of the band pass filter passes through the filter(102a). The output signals of the band pass filter is down-shifted by the mixer and filtered by the filter such that only the signal corresponding to the channel '1' passes through the filter.
