FIELD: TV equipment. SUBSTANCE: device has stepping-down frequency converter, which has local oscillator, which is controlled by automatic fine tuning signal. Its output is connected to picture channel and sound channel, including filter with saddle characteristics, clipper, and frequency rejection filter, which generates quadrature response to picture carrier of clipped signal used for detector which generates sound signal, and for detector of automatic fine tuning. EFFECT: simplified design. 4 cl, 8 dwg
