ABSTRACT:
A mobile radio wave receiver including an automatic gain control amplifier, an electric field intensity detection circuit, an error correction circuit, and an error correction error detection circuit is disclosed. The automatic gain controlling is selectively effected in accordance with the detected electric field intensity and a degree of the detected error correction errors. The mobile radio wave receiver further includes a bandpass filter with a first variable bandwidth and a waveform shaping circuit with a second variable bandwidth, wherein the first and second variable bandwidths are controlled in accordance with the detected electric field intensity and the degree of the error correction errors.
