19.5Â Work through Programmed Exercise 18.1using an SM chart instead of a state graph.
19.6Â Solve Problem 18.6 using an SM chart instead of a state graph.
19.7Â (a) For the SM chart of Figure 19-9, make the following state assignment for the flip-flops Q0:
19.8Â Â Q1:
19.9Â Â and Q2:
19.10 :
Â
S0: ooo; S1Â 001; S2Â : 100; s3: 101; S4Â : 110; S

Derive the next-state and output equations by tracing link paths on the SM chart.Simplify the equations and, then, draw the circuit using D flip-flops
and NAND gates.
(c)Â Â Â Â Â Â Â Â Repeat for the SM chart of Figure 19-10, using the following state assignment for flip-flops Q0:
(d)Â Â Â Â Â Â and Q1:
(e)Â Â Â S0: oo; S1: 01; S2Â :11; s3: 10.
