I am trying to design a logic circuit that will output a 5v, 2 second pulse when it receives the leading or trailing edge of a 5V varying (5 to 60 sec) pulse. This is an application for the activation/deactivation of the R/R crossing lights and crossing bells sound card of a model train layout.
I had a lot of training in logic circuits decades ago but I seem to have misplaced a lot of that knowledge from lack of use over the last 20 years.
I'm familiar with transistors, gates and all the hardware that goes into circuits but can't put them together to get the correct end result.
Thanks,
