The circuit comprises an amplification section (1), a buffer section (2), resistor elements (3,4), a band pass filter (5), a limitter (6), and an adder (7). The luminance signal input terminal (a) is connected with the bases of TR1, TR2. The output of the amplification section is coupled to the band pass filter and the bases of TR6, TR5, through R3, R4. The limitter is connected with the bases of TR7, TR9 in the adder, and The emitter of TR4 is linked to the connecting terminal of R10, R12 in the adder.
