Fig. 3-3 is a Moore type sequential circuit composed of a positive edge triggered D flip-flop and a combinational circuit. X is input, Y is an output, and CLK is a clock. Please show how Qo, Q1, and Y change when input X is given to this circuit at the timing diagram shown in Figure 3-4.
I got the answer is y=0 but in timing diagram it is not zero why?
my attempt to draw timing diagram
Why y is not zero in timing diagram?
Figure 3-5 shows the state transition diagram of Moore type sequential circuit M that observes the time series of input X and outputs 1 when time series 010 or 101 appears, and 0 otherwise (Incomplete). Let S0 be the initial state (assume that 0 is input consecutively twice or more consecutively) and complete this state transition diagram according to the notation without increasing the number of states. Note that the time series will continue indefinitely.
Here i really dont understand what the question want?
Should i make 010/101 from the diagram?
Can someone give me hint?
