Q2. It is required to design a sequence detector that detects overlapped occurrences of the sequence 10010. The circuit receives a serial input X and produces a serial output Z. The output Z will be 1 when the circuit detects the sequence 10010. Assume the existence of a reset input to reset the machine to a reset state. Draw the state diagram of the circuit assuming a Moore model. The following is an example of some input and output streams: Input X 0010010010 1 0 0 1 00 Output 0000 0 0 010010 00 0 1
