Hello all and apologies for what may be a very simple question.
I have a micro controller that produces a very short (say 2 or 3 millisecond) 5 volt pulse every now and then. The signal occurs only upon the occurance of certain events by design, so is not cyclical or otherwise predictable.
I would like to capture and log when these pulses occur, but my data logger only samples 50 times per second and therefore misses some of these short pulses.
My question is-- how can I extend the length of the pulse to about 1/50th of a second to ensure my data logger captures each pulse? Each pulse occurs infrequently, so I'm not worried about missing one during the time the pulse is extended. Also, the voltage of the pulse can decay over the extended pulse time, as long as it remains above 2 volts for at least 1/50th of a second.
All help appreciated!
