Abstract
PURPOSE: To make it possible to monitor surely the period of pulses by setting previously trigger states of the first and the second retriggerrable monostable multivibrators.
CONSTITUTION: Input signal A is applied to input terminal A1 of the first monostable multivibrator 10, and the output Q1 is sent to input terminal A2 of the second monostable multivibrator 20 and is outputted from Q2. These monostable multivibrators 10 and 20 are retriggerrable, and monostable multivibrators 10 and 20 have trigger states set by a period time shorter than the normal pulse period of the input signal and a period time longer than the normal pulse period of the input signal respectively. Consequently, the period can be monitored surely without clear clocks.
