NTE799
Integrated Circuit
Four Channel “SQ” Decoder
Description:
The NTE799 consists of two high input impedance preamplifiers which are fed with left total, LT, and
right total, RT signals. The preamplifiers each feed two all–phase networks which generate two LT
signals in quadrature and two RT signals in quadrature. The four signals are matrixed to yield left front,
left back, right front, and right back signals (LF, LB, RF, RB).
