I'm having trouble with this question. Any help will be appreciated.

A device that acts as a many bit shift register while accepting serial logic voltages is?

1 Analog switch
2 Hall effect device
3 push-pull amp
4 charge coupled device

My hunch is 1, any hints or info, big thanks.

 

Hello,

Have a look at the respective pages of the wiki:
http://en.wikipedia.org/wiki/Analogue_switch
http://en.wikipedia.org/wiki/Hall_effect
http://en.wikipedia.org/wiki/Push–pull_output
http://en.wikipedia.org/wiki/Charge-coupled_device

What will be your conclusion after reading them?

Thank you, got it. Its a CCD, found it in my book as well as Wikipedia. Thank you very much.

 

While CCD is clearly the answer, I think the question could be much better written since a CCD works not just with "logic" voltages (which implies just the voltages associated with logic levels), but with analog voltages having nothing to do logic at all.

 

Yeah some of the questions are a bit awkward. Here is what is funny about Electronics that I have found. I could ask a pretty normal electronics question in multiple forums and will get many different interpretations from experienced Electronics technicians. I often get also "that questioned could have been asked this way instead and have been more clear, but its all in the way the author was taught". I find that fascinating, it tells me Electronics is complicated, and takes a few technicians sometimes to get to the right answer, or to get to the right solution.
My friends are are absolutely floored by how much is involved with this ET program. I mean its something like 75 books, 52 exams and its not easy. They are floored by how much info there is to learn about Electronics.

 

I believe that:
(1) What you are saying is absolutely true.
(2) It is far from restricted to just electronics.

If it weren't really widespread, out legal system would be a LOT less busy!

 

Thanks again WBahn, interesting observations. This may sound corny, but I find Electronics fascinating. This program is fascinating, I had no idea what i got myself into when I started this program but its been some learning experience. 6 more exams and roughly, 12 more books and I get my diploma.
