Abstract

PURPOSE:To insert a data pulse without burying it even in any video signal level by inputting the data pulse and lowering the video signal level simultaneously. CONSTITUTION:A data inserting OR circuit si constituted of a first amplifier 1 and transistors Q3, Q4. A comparator is constituted of a differential transistor pair Q6, Q7 and a bias current source I4, a reference voltage is applied to the v base of the transistor Q6 and the data pulse is applied to the base of the transistor Q7. When the data pulse exceeds the reference voltage, the base voltage of the transistor Q3 is lowered. Accordingly, at the time of inputting the data pulse, a video signal is attenuated.
