Patent ID: 8494471

Claim:
A receiver comprising: a first frequency changing circuit for converting a received signal including two or more broadcast waves into a first intermediate frequency signal; a band separation filter consisting of a multistage FIR type filter for allowing bands included in the two or more broadcast waves converted into said first intermediate frequency signal to pass therethrough simultaneously; and a second frequency changing circuit for converting the received signal which is outputted by said band separation filter and which is limited to said two or more broadcast waves which said 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 when processed by OFDM (Orthogonal Frequency Division Multiplexing) demodulation, wherein a delay time provided by delay circuits which construct said FIR type filter is a reciprocal of a frequency which is one-2nth (n is an arbitrary integer) of an entire channel band shown by a difference between a lowest channel of said received signal and a highest channel of said received signal.
