Receiver and a method of attenuating a disturbance signal by a trap circuit having its resonance frequency adjustable |
摘要 |
A receiver for receiving a radio frequency signal includes an attenuator for attenuating a disturbance signal such as an image signal which causes disturbance to a received frequency of the radio frequency signal, on the basis of set information of the received frequency. The attenuator includes a trap circuit for producing a resonance frequency in accordance with the set information. The trap circuit is connected on a supply line for the radio frequency signal and suppresses the disturbance signal by the resonance frequency.
