SOUND PROCESSOR with SOUND ENHANCEMENT
■■■■
GENERAL DESCRIPTION
The NJW1130A is a sound processor with sound
enhancement (BBE). It includes all of functions processing
audio signal for T V, such as tone control, balanc e, volume,
mute, and AGC functions.
Also the NJW1130A performs surround and sound
enhancement. The sound enhancement regenerates high
definitive and nearly real sound.
All of internal status and variables are controlled by I
2
C
BUS interface.
