I agree, if we talk about designing a A/D system, but if one finds a
chip with a good application report with already designed pcb it would
not be to hard to do it.
Just make a pcb after the pattern, and solder the components.
With a little luck it will work without problems.
I think it would be possible to find such a ready-made design if one
searches for it.
Beside applications reports there are probably amateur A/D projects
descriptions around somewhere which could be used.
Project descriptions in magazines like Elektor is another source.
They might even sell a readymade pcb for the project.
There is also the possibility of buying a readymade ADC card for a PC,
even if it costs more it would be cheaper than a real scope.
And I think there is free software which can be used, if it is not
delivered with the ADC card.
It is very much a question of how well you can search the net, and
public libraries, for what you need.
