Radio receiver
Abstract
Abstract A radio receiver has an antenna circuit, a high-frequency amplifier, a tuned circuit, a mixer for generating a first intermediate frequency signal, and an AGC circuit applied with an output signal of the radio receiver for controlling a gain of the receiver. An intermodulation predicting circuit is provided. The intermodulation predicting circuit has a high-frequency amplifier applied with an output of the radio receiver, and a mixer for generating a second intermediate frequency signal. The intermodulation predicting circuit has a dynamic range smaller than that of the radio receiver. Therefore an intermodulation prediction signal based on a received broadcasting signal is produced earlier than a response to the received broadcasting signal at the radio receiver.
