Abstract

PURPOSE:To increase the upper limit of the using frequency, by analyzing an input pulse signal train into plural pulse signal trains of a long period, expanding the pulse duration to transfer the pulse signal trains via different photocouplers respectively and converting and synthesizing the pulse duration. CONSTITUTION:An input pulse signal train applied to an input terminal 1 is analyzed into two pulse signal trains of a long period by means of the pulse analyzing signal applied to an input terminal 2, an inverting circuit 5 plus NAND gates 3 and 4. Then the pulse duration of the pulse signal train is expanded by monostable multivibrators 6 and 7, and the pulse signal trains are transferred via photocouplers 8 and 9 respectively. The transferred pulse signal trains are applied to monostable multivibrators 10 and 11 respectively, and the pulse duration is converted in the same way as the input pulse signal train. After this, the outputs of the vibrators 10 and 11 are synthesized at an NAND gate 12.
