Abstract
A receiver apparatus includes a band-pass filter having a variable frequency band coupled to a node for receiving a received signal including a plurality of channels to output at an output node thereof a limited-band signal made by limiting a frequency band of the received signal to a frequency band of a desired channel, a frequency conversion unit coupled to the output node of the band-pass filter to output at an output node thereof an intermediate frequency signal made by converting frequencies of the limited-band signal, and a control unit configured to adjust an intermediate frequency of the intermediate frequency signal by controlling the frequency conversion unit in response to at least one of a signal speed and a channel frequency interval of the received signal.
