Patent ID: 8326248

Claim:
An analog radio receiver, comprising: an IF filter for eliminating unnecessary signal components from an IF signal defined at a specific intermediate frequency; a demodulation processing unit for demodulating a signal outputted from said IF filter into a sound signal; a sound category determining unit for determining a category of a sound to be reproduced from said sound signal outputted from said demodulation processing unit; a selecting unit for selecting a noise suppression parameter on the basis of said category of said sound determined by said sound category determining unit; and a noise suppressing unit for setting at least a width of a passband of said IF filter on the basis of said noise suppression parameter selected by said selecting unit such that the width of the passband is selected based on said category of said sound, wherein said IF filter eliminates said unnecessary signal components from said IF signal on the basis of said passband set by said noise suppressing unit.
