| Zusammenfassung: | A receiving apparatus that includes a first and second filter circuit. The first filter performs filtering on a frequency signal with a band-pass characteristic such that a frequency band of a desired channel is included in a passband, thereby obtaining a pass frequency signal. The second filter performs filtering on the pass frequency signal with a filter characteristic such that a frequency band of a channel adjoining the desired channel is included in an attenuation band. |
