An intermediate-frequency (IF) coupled-circuit for a television tuner is provided,
which is connected between an IF amplifying stage and a video-signal-selection
filter, and which comprises a parallel circuit having a second capacitor connected
in parallel to a series circuit having a resistor for impedance matching, an inductor,
and a first capacitor which are connected in series, wherein the series circuit
resonates at the frequency component of the selected channel, and the parallel
circuit resonates at the frequency component of the channel lower than and adjacent
to the selected channel, thereby functioning as a trap for removing the frequency
component of the channel lower than and adjacent to the selected channel.
