AUDIO PROCESSOR with SOUND ENHANCEMENT
■
■■
■ GENERAL DESCRIPTION ■
■■
■ PACKAGE OUTLINE
The NJW1132A is a sound processor with sound
enhancement (BBE). It includes all of functions processing
audio signal for TV, such as tone control, balance, volume,
mute, and AGC functions.
Also the NJW1132A performs surround and sound
enhancement. The sound enhancement regenerates high
definitive and nearly real sound.
All of internal status and variables are controlled by I2C
BUS interface.
