A received circuit receives a plurality signals generated by modulating carrier waves having the substantial same frequency according to digital signals having different bitrates output from a plurality of systems. The receiving circuit includes a front-end portion that tunes and outputs the signals received by an antenna; an analog-to-digital converting portion that converts the signals output from the front-end portion to digital signal processing portion that processes and demodulates the digital signals; and a plurality of digital filter portions each of which extracts a digital signal output from a corresponding the plurality of systems, from the demodulated signals output from the signal processing portion, based on a bitrate of the digital signal output from the corresponding system.
