The LM1894 is a stereo noise reduction circuit for use with
audio playback systems. The DNR system is noncomplementary,
meaning it does not require encoded source
material. The system is compatible with virtually all prerecorded
tapes and FM broadcasts. Psychoacoustic masking,
and an adaptive bandwidth scheme allow the DNR to
achieve 10 dB of noise reduction. DNR can save circuit
board space and cost because of the few additional components
required.
