Injection and sampling

[Gixxerdan]

Hi,
I am currently doing my NVQIII and one of the questions is asking about various fault finding techniques and how you apply them. One that i am stuck on is injection and sampling. Could anyone please tell me what this is? thanks

hi there

injection would rcd testing as you inject a fault current to trip it and i thin k so testers may sample certain test mathematically

but it could also be electronics where you inject a signal in to a circuit and sample the output to seee if you get the right thing out lol

cheers
