... tatge level). The trigger input involves switching a constant positive voltage to zero. Once triggered, the output pulse begins and further trigger inputs will be ignored until the output pulse is completed. The length of the output pulse has no relationship to the length of the trigger input. This circuit uses the 555 timer IC. The length of the output pulse depends on the values of R and C. The formula for determining the length of the output pulse is output pulse length = 1.1RC MONOSTABLE MODULE The monostable module controls the width of the trigger pulse, which is synchronised to the clock signal of the data acquisition board. It is based on dual monostable multivibr ...
