The circuit is for generating a black burst signal by using a voltage divider composed of resisters. The circuit comprises a horizontal signal generator for dividing voltage level of input horizontal synchronous signal to generate a black burst horizontal synchronous signal, a burst signal generator for dividing voltage level of a carrier signal to generate burst signal, and a black burst signal generator for switching output signals of the horizontal signal generator and the burst signal generator alternatively to generate black burst signal.
