7. [10 pts] Mealy sequential machine has following state table: NS Z PS| X=0 X = 1|X=0 X = 1 123 2 3 CLK X PS 2 221 N 2 1 321 1 3 2 Complete the following timing diagram. Clearly mark on the diagram the times at which you should read the values of Z. All state change occurs after the rising edge of the clock. You should put 1, 2 or 3 for PS and NS, and 0 or 1 for Z (for each half-cycle). Initial states given below. and values are 1 1 NS 2-3 0--0 0 0 1 0 0 0 1 I I T 1 I " T I 1 I 1 I I I I 1 1 1 I
