Abstract
A radio receiver device includes a radio signal processing section and a digital processing section. The radio signal processing section converts a received radio signal into a digital signal, demodulates the digital signal and detects a S/N ratio of the radio signal. The digital processing section digitally processes digital signals and switches over its operation mode based on the detected S/N ratio, thereby controlling a digital noise generated in the digital processing. The radio processing section checks whether the S/N ratio is lowered by a digital noise of the digital processing section or a shielding body external to the radio receiver device. The digital processing section switches over its operation mode to reduce the digital noise only when the cause of the fall of the S/N ratio is caused by the digital noise.
