S0 is state zeroWhat is SO? Is it a control signal? Post a complete state diagram or truth table.

Present state input next statePost a state diagram or truth table.
Let present state 00 and input 1 and previous input 1. Then next state is 01.View attachment 169136
It kind of looks like you want a circuit that counts when the input is 1, but the second line in the table is problematic. If the next state from 00 is 00, that conflicts with the next line that goes from 00 to 01.
For a simple state machine (which is what it appears you are trying to create), the knowledge of what state you are in has to capture ALL relevant information about the ENTIRE history of the machine. So as soon as you say that, when in State 00 and the current input is 1, you do different things depending on what the prior input was, you have a situation in which just knowing that you are in State 00 is insufficient knowledge about the history of the machine to determine what to do next based on just the current input.I am trying to design a sequential circuit that starts with SO (00) and next state is 00 when input is 0. When input is 1, states go like 00--00--01--11--10
I dont know how to handle input=1 because next state can be 00 or 01 both. What can I do?
