I can't get this problem right... This problem was given by my professor as a possible exam question. I took a considerable amount of time thinking in it, but I'm yet unable to solve it. The problem is the following: Build a circuit that accepts a square wave as input and outputs a square impulse when the input reaches a rising edge(or at the falling edge, or in the middle of the square).
Since English is not my native language it may be better explained by this image:
So far the most complex circuit components we have learned are opamps and diodes(normal and zener).
I've tried everything I remembered but the closer I got was a simple impulse...
