Fig.2 Block diagram of the bipolar TV/VTR-stereo decoder with fixed coil (alignment-free).
Input and output levels are nominal values related to the SCART norm (AM: m = 0.54, FM:
f= ±27 kHz).
The components of the external LC band-pass filter have the following order-No.: Philips Germany only No: 4312 020 17525 or Fastron Sdn. Bha., Malaysia type SMCC 472 J
for L = 4.7 MHz (
±5%) Philips Components No: 2222 429 71802, C = 1.8 nF (±2%).
