right... i need to make a programmable digital delay circuit that can delay a pulse by a few nanoseconds. sorry if any of the following info is vague, I am only an apprentice and i have taken this on as a college project, but the poduct will be used at work in a calibration lab, but i am not too knowledgeable as of yet so I am very much an amateur.
anyhoo, what it will be used for is calibration of TDR's/cable testers. i need it to be able to take in a pulse and delay it by a programmable amount, down to about a 10ns delay. i know a product exists for this, but buying a product is no fun :) not to mention expensive...
it will need to take in the pulse from the TDR, delay it, and send it back. this will replicate the function of the TDR in real conditions.
as i mentioned it will need to be programmable, possibly by means of a binary input (so I've been told :s)
im still in the mind mapping stage, if you want to get technical then great, but even small pointers will be greatly appreciated. circuit schematics, specific ICs, i will accept anything
thanks in advance
