Hello guys..
I'm studying digital logic design basics this semester..and I have some questions that need logical answers.first,I want to ask about latches.How do they store a bit,is it stored in the feed back loop.Also,I did an experiment on LogicWorcks, I constructed an sr latch-type doesn't matter I guess-and I connected the output to a binary probe...after I had a value for the output.I disconnected the latch from the input switch...and I had an X at the probe.I did same thing to a flip flop but it stored the output..it didn't lose it.
The other thing is when I construct a latch or FF-whatever-whith out touching the outputs...what would I get for the outputs..(especially for jk flip flop whe n j=k=0 I would have the current state,but here is the problem...what is it?
I'm sorry I asked a lot of questions.But I really need answers because my head is spinning right now .
