... The TDA8417 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 TDA8417 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) ...
