Electonics Products GCSE AQA 21st June 2012

What did everybody think of the preliminary material? Any ideas of what product you're going to do?

what is the preliminary material? i never got it lol and im doing aqa

You need to colour it in to get top marks xD

for the process block of INPUT-PROCESS-OUTPUT, what kinds of stuff do you have to write? i know input would be like PTM switch and output could be LED's or something but I don't get the process part

EG, astable, decade counter

so what if it was just a PTM switch to complete the circuit?, what would you write then?

What do u mean?
eg
PTM = input
Output = LED
Process - Monostable

but would saying something like 4026IC be a process?

My answer wasnt up to par tbh. This is from the mark scheme.

comparator, level detection, latch, delay, oscillator
Detector or suitable specific process component, logic gate

That stuff is more or less guaranteed to get you marks. On one exam, I put astable and didnt get the mark, although its basically an osicaltor.

oh ok thanks, a delay is a monostable anyway isn't it? and comparator is like a op-amp?

what about a PIC? that would work right?

I don't know - I'm not a teacher, but to me it seems a bit general - what will the pic do for instance. That list i provided was from the JUne 2011 mark scheme, so I recommend sticking to that, but, again, I'm not a teacher. However, my electronics teacher has set up some forums, so you could check them out - just ask if you want a link
