Hello! I've attached screenshots of my attempt to recreate a circuit in a simulator using everycircuit.com
Firstly, is a square wave the same as a trigger pulse?
The square wave on the simulation is 1V HIGH, 0V LOW with a period of 1ms (these are the default values, I'm not sure what to change them to)
I added a switch so that I could see the output at a steady state before the square wave should come in to change the output but unfortunately I can't seem to get it to behave this way.
I think I have to generate a negative input at the inverting terminal of the op amp in order to trigger the output to change from -15V to 15V but I'm not sure how to do that, is there a way to calculate what the value of Vin should be in order for this to work?
Any advice would be greatly appreciated,
Thank you
