Abstract

PURPOSE: To obtain a video signal allowing invariably-normal television picture reception by stabilizing the operation of a synchronous separator circuit by effectively removing a noise component from a video signal with a superposed noise.
CONSTITUTION: An input signal is applied to the base of 1st transistor 1 with level-shifting diode 2 and 1st voltage dividing methods 8 to 10 at the emitter side, its output is inputted to the base of 2nd transistor 6 with 2nd voltage methods at the emitter side, and the base of 3rd transistor 7 is connected to the base of 2nd transistor 6 via the middle point of 3rd voltage dividing methods 16 and 17. Then, the differential amplifier is formed of 4th transistor 4 and 5th transistor 5 and when transistor 5 is ON, one-side terminals of the 3rd voltage dividing methods 16 and 17 are connected together via switch circuit 18; and capacitor 15 is connected between the power supply and the middle point of 2nd voltage dividing methods 13 and 14.
