A receiver 1 is comprised of a first frequency changing circuit 13 for converting a received signal including two or more broadcast waves into a first intermediate frequency signal with a local oscillation, a band separation filter 14 consisting of a multistage FIR type filter for allowing bands included in the two or more broadcast waves converted into the above-mentioned first intermediate frequency signal to pass therethrough simultaneously, and a second frequency changing circuit 15 for converting the received signal which is outputted by the above-mentioned band separation filter 14 and which is limited to the above-mentioned two or more broadcast waves which the receiver desires to receive into a second intermediate frequency signal from which each of the broadcast waves can be sampled at a frequency at which the broadcast waves do not interfere with one another.
