资 源 简 介
The LM1894 is a stereo noise reducTIon circuit for use withaudio playback systems. The DNR system is noncomplementary,meaning it does not require encoded sourcematerial. The system is compaTIble with virtually all prerecordedtapes and FM broadcasts. PsychoacousTIc masking,and an adapTIve bandwidth scheme allow the DNR toachieve 10 dB of noise reduction. DNR can save circuitboard space and cost because of the few additional componentsrequired.
