I have seen this model question on synchronous circuit , but i could not understand the logic, can anyone please help me?
"Develop the state diagram for a synchronous sequential circuit which will recognize the bit sequence 1101 (ie, every time the sequence 1101 is detected in the input bit stream, the circuit has to output a 1 and otherwise a 0)."
What is the question here?? do we have consider all possible combinations ( 2^4 - 16 ) to do this ? if so , according to the question , do we have only one occasion where we get the output 1??
please explain it. -Regards
