Abstract
PURPOSE: To make unnecessary the time constant circuit and to make suitable for circuit integration, by controlling the counter value of the pulse width counter through the use of the converted pulse and determining the width of conversion pulse through the comparison of it with the count value of the reference counter.
CONSTITUTION: The input terminal 21 is connected to the clock circuit 22 and also to the register 24 directly, and the clock pulse or reset pulse produced at the circuit 22 is fed to the pulse width counter 23. Next, the output of the counter 23 is fed to the register 24 and this output is fed to the comparison circuit 28. On the other hand, the input terminal 25 of the reference pulse is banched and connected respectively to the reference clock pulse generation circuit 26, reference counter 27 and inversion circuit 29, and the output of the circuit 26 is fed to the circuit 28 via the circuit 27, and this output is fed to the inversion circuit 29 connected to the output terminal 30. Thus, the pulse P inputted to the terminal 21 is in synchronizing with the horizontal synchronizing signal H fed to the terminal 25 to pick up from the terminal 30 as the dignal Q of different width.
