I have read some posts like: What is state in a sequential circuit? about explaining what a state is in the sequential logic circuit. But the responses are pretty much the same as those ones in my textbook and I still don't understand what it is exactly.
From my understanding so far, I think a state is pretty much like the mode of a circuit when some certain inputs are given. For example, if we have a two-inputs SR latch, when S and R are 1 and 0, SR latch is in the set state, which I think it's like the circuit is in the setting/saving mode. (not sure if this understanding is correct or not)
But if this understanding is correct, I found out it is so weird to read my textbook. (Digital Design and Computer Architecture, second edition, David Money Harris)
"The chapter begins by studying latches and flip-flops, which are simple sequential circuits that store one bit of state." If state is similar to the concept of mode, why we can tell how many bits are there in a state?
Can someone please give me an accurate definition about the state? If it is possible to provide an analogy I will be really grateful, this would really help me understand this stuff.
