A sequential circuit has the form shown in Figure 13-17 with D1 = Q2Q3 + XQ1 D3 = Q2 + X D2 = Q3 + XQ2 Z = XQ2 + XQ2 Analysis of Clocked Sequential Circuits 447 (a) Construct a state table and state graph for the circuit. (b) Draw a timing diagram for the circuit showing the clock, X, Q1, Q2, Q3 and Z. Use the input sequence X = 01011 and assume that X changes midway between falling and rising clock edges. Indicate any false outputs on the diagram. (c) Compare the output sequence obtained from the timing diagram with that from the state graph. (d) At what time with respect to the clock should the input be changed in order to eliminate the false output(s)?
