PRELIMINARY

SOUND PROCESSOR with SOUND ENHANCEMENT

GENERAL DESCRIPTION

nnnn

NJW1132

The

is a sound processor with sound
enhancement (BBE). It includes all of functions processing
audio signal for TV, such as tone control, bal ance, volume,
mute, and AGC functions.

Also the

NJW1132

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
