For example, if we have a OR gate, one input depends on us and the other input is like the feedback from the output, how can we generate the truth table? Thank you!
If it starts from initial state and say Controlled input is 0= then output will be latched to 0. Because the controlled input is 0 and the fed back value is also 0. There is no way the fed back value could be set to 1 without changing the controlled input.
Once you set control input to 1- no matter what the feedback it- it will latch to 1 for ever.
Are you looking to make a latch?
Controlled Fed back Out
0 0 0
0 1 1 : This case is invalid in the beginning when Controlled lines do not change. Coz how will output change if Controlled input is 0!? Do you get what I mean?
Once the controlled input is set to 1 then output will be 1 for rest of the cases, even if you switch the controlled line to 0. (The case above becomes realistic).
yes andre is correct... this is sequential design and cant be explained by combinational approach.
yes. you are. are you trying to design an latch or FF???
Not in time domain, because is latched.
Output depends on Previous State and Present Input. you can find about it in almost all basic books or on google. pretty easy to understand.
