NJW1130A
PPRELIMINARY
SOUND PROCESSOR with SOUND ENHANCEMENT
s
GENERAL DESCRIPTION
The
NJW1130A
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
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 C
BUS interface.
