S SteveyD New Member Oct 17, 2010 #1 Hello I'm working on a counter circuit and I would like to make 1 input pulse become 2 output pulses. I'd prefer not to use a microcontroller if I don't need to. Any suggestions?

MikeMl Well-Known Member Most Helpful Member Oct 17, 2010 #2 A CMOS exor gate where one of the inputs gets your existing clock signal and where the other input gets the same clock delayed by passing it through a series R and shunt C delay...

Reloadron Well-Known Member Most Helpful Member Oct 17, 2010 #3 The circuit you linked to is a counter that will count 0 through 9 over and over again. I don't quite get what you are asking: 1 input pulse become 2 output pulses Click to expand... What exactly are you trying to do? Edit: Maybe Mike has it right if that is what you are after.

S SteveyD New Member Oct 17, 2010 #4 Using the circuit linked in the first post, I'd like to have the trigger input pulse advance the counter x2, instead of x1. So instead of counting by 1's, it counts by 2's. (2,4,6,8, etc)
