Hello,
I need a circuit which consists of: differentiator, peak hold, and comparator which will convert signal to digital.
The circuit must take 2 analog inputs which are updating at 450 times per second (4 to 20mA or 0 to 10V) and run them through differentiators in order to get the slope of the signal. Then the slope of the signal needs to go through a peak hold.
If the peak slope is under a value it should be ignored, if the peak hold is above the ignore value and below an alarm value it should turn on a good output and the peak value should be cleared after 6ms, if the peak value is above an alarm value it should turn on an alarm output for 6ms and be cleared.
This page is great. I recommend it to everyone. Congrats.
