Hi,
I need help to detect this FLIP FLOP.
a, b and c are inputs, and e and d are outputs.
It could be RS, D, T or JK flip flop.
Thanks in advance

hi Alma,
Welcome to AAC.
Looked at your image, what is your question.?
I do not know what you mean by 'help to detect'.

E

EDIT:
Do you have a image from the book showing counter circuit, to post.??

This is from thw book. I have to answer which flip flop is this according to the inputs and outputs. I used truth table for every flip flop but I still can't figure out which one is it

hi,
OK, I understand, you have to work out which type of FF counter/divider would give this output pattern.

I know that. But only JK and RS have 3 inputs but none of them have 2 outputs (just Q and Q'), but d is not inverted e. So I really dont know

hi,
Checking the image you posted.
If the top 3 traces are Inputs and the bottom 2 traces are the outputs, and assuming one of the top 3 is a Clock input, the outputs do not follow any one of the 'edges' of the top 3 traces.???

I see changes in the outputs that do not follow any possible clock pulse.

Is there any more information in book, that you could post.?

I assume one is clock but really dont know. And there is nothing else in there. Just this

I think I figured it out. I thought it could only be flip flops, but I think this is actually full adder. 3 inputs and 2 outputs
