I want to make a digital circuit to detect if a clock is toggling or not. Basically, it outputs a "1" as long as the input is toggling and "0" if not? Sort of like a mono-stable one shot but using digital logic only. I know how to make the circuit to detect the toggling and output a "1" but once the clock stops, I need to reset my output. This is the part I havn't been able to figure out yet. Anyone done this type of circuit before? please :idea:
This is exactly what I need to do but unfortunately I don't have the 2nd clock. There may be other solutions to this problem such as delay lines and flops?!!!
