Abstract

PURPOSE: To perform suitable alarm, by outputting the output of non-signal after a given time elapsed further, after random signal is shaped into rectangular wave and a given time is elapsed from the time point when the rectangular wave is inputted and the random pulse is incoming during this time.
CONSTITUTION: The random signal is sliced with the slicer U1 to be rectangular wave signal. This rectangular signal is fed to the alarm control circuit U2 and the signal without random wave is outputted to the alarm U3 when a given time is elapsed from the time when the rectangular signal is inputted. Simultaneously, as far as the succeeding rectangular wave within a given time is present, the signal without random wave is not outputted and when the non-signal state of random wave continues more than a given time, then the signal without random wave is outputted. The alarm unit U3 turns on the switching element when the signal without random wave is inputted to operate buzzer.
