adjustable delay recopy

Jun 02, 2006 3 Replies

Hi,



I have to transmit a signal ( 0-10V pulse ) with an adjustable delay around few milliseconds.



My input is 0-10V pulse and my output is simply the same retarded pulse.



Is there a simple way to do that with an analog schematics or existing IC.



Thanks


It's helpful if you explain the application. When people say "I have to..." it makes us think it's a homework problem.

What's the pulse rate like?

There\'s an error in the reset circuitry. This\'ll fix it and use up the spare gates.
