LM1894 Dynamic Noise Reduction System DNR

LM1894 Dynamic Noise Reduction System DNR



INTRODUCTION

The operating principles of a single-ended or non-complementary audio noise reduction system, DNR, have been covered extensively in a previous application note AN384, Audio Noise Reduction and Masking. Although the system was originally implemented with transconductance amplifiers (LM13600) and audio op-amps (LM387), dedicated I/Cs have since been developed to perform the DNR function.
