METHOD FOR REDUCING NOISE INCLUDED IN A STEREO SIGNAL, STEREO SIGNAL PROCESSING DEVICE AND FM RECEIVER USING THE METHOD |
摘要 |
Method for reducing noise included in a stereo reproduction signal derived from a stereo input signal characterized by the steps of: *varying stereo channel separation of said stereo reproduction signal with frequency within the frequency range of the stereo input signal in accordance with the frequency response of a filter selectivity located around a center frequency to obtain a stereo channel separation peak value at said center frequency; *at a continuing increase of said noise, decreasing the bandwidth of said filter selectivity to a pre-determined non-zero bandwidth while maintaining the channel separation within the bandwidth of said filter selectivity substantially at said channel separation peak value. |
