1 input pulse becomes 2 output pulses. How to do it?

[SteveyD]

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?

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...

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

What exactly are you trying to do?

Edit: Maybe Mike has it right if that is what you are after.

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)

Mike,

So perhaps a 555 in this fashion with pin2 as the input and not closed?

Simple RC delay + schmitt trigger + OR gate w/original pulse.

Simple RC delay + schmitt trigger + OR gate w/original pulse.

As MikeML stated it needs to be an Exclusive OR gate, not a standard OR gate.

Yeah, that would be better.
