• 3-stage gain controlled i.f. amplifier
• A.G.C. circuit
• Reference amplifier and limiter amplifier for vision carrier (V.C.) processing
• Linear multiplier for quadrature demodulation

2nd i.f. (5,5 MHz signal)
• 8-stage limiter amplifier
• Quadrature demodulator
• A.F. amplifier with de-emphasis
• AV switch
