  • Synchronizing For Television (AREA)

Abstract

PURPOSE: To simplify a circuit which converts the width of a vertical synchronizing signal into 3H as to a television screen display unit, by constituting the circuit by combining an integrating circuit, a differentiating circuit and a transistor.
CONSTITUTION: To input terminal 31, differentiating circuit 34 composed of capacitor 32 and resistance 33 is connected, to which transistor 36 is connected to via resistance 35. The collector of this transistor 36 is connected to the +B power supply via resistance 37, and its emitter is connected to transistor 39. In addition, transistor 42 is connected to input terminal 31 via the parallel circuit of capacitor 41 and resistance 40, and the collector of this transistor 42 is connected to the +B power supply via resistance 43, to the base of above-mentioned transistor 39 via integrating circuit 46 of resistance 44 and capacitor 45 and resistance 47, and to transistor 53 via differentiating circuit 51 of capacitor 49 and resistance 50 and resistance 52.
