Abstract

PURPOSE:To obtain a signal having a high stability with an extremely reduced phase distortion, by installing a monostable multivibrator circuit that uses the synchronous timing signal row for the input and reproduces and decodes the output timing signal row of the rectangular wave. CONSTITUTION:The synchronous timing signal 6 which received a code conversion and modulation by the timing index system is received at the input terminal 5 and applied to the monostable multivibrator circuit 10. The circuit 10 is triggered by the rise of the signal 6 and produces an output signal having a pulse duration that is decided by the capacitor 12 and the time constant circuit of the variable resistor 13. In this case, both the capacitor 12 and the resistor 13 select such value as to deliver the rectangular wave. Then the timing signal row of rectangular wave is transmitted through the output terminal (a).
