GENERAL DESCRIPTION
The TDA8415 is a processor of stereo/dual language
signals (B/G-standard) for stereo sound television
receivers and VTRs, using the switched-capacitor
technique. The AF signals at the TDA8415 inputs must be
“(L R)/2” or “language A” on one channel and “R” or
“language B” on the second channel (where L = left and
R = right). The carrier frequency of the second channel is
also modulated by an identification signal (stereo or dual
sound). The device is controlled by a microcomputer via
the two-line, bidirectional I
