A device, system, and method for improving the performance of a tuner for
a selected channel by providing a band selection filter controlled by a
digital voltage, instead of a notch filter for controlling FM radio
signals. The tuner includes a band-selection filter module for selecting
a radio frequency RF signal having a frequency within a frequency band of
the selected channel using a voltage determined based on digital
information; an amplifier module for amplifying the selected RF signal; a
mixer module for down-converting the amplified RF signal into a signal
having a frequency within an intermediate frequency (IF) band, in which
the digital information corresponds to the frequency band of the selected
channel.
