Present | Next state | Output | ||
---|---|---|---|---|
state | 0 | 1 | 0 | 1 |
a | f | b | 0 | 0 |
b | d | a | 0 | 0 |
d | g | a | 1 | 0 |
f | f | b | 1 | 1 |
g | g | d | 0 | 1 |
Note: Equivalent states: b=e, a=c, h=d
(a) Draw the corresponding state diagram.
(b) Tabulate the reduced state table.
(c) Draw the state diagram corresponding to the reduced state table.
2- A sequential circuit has two JK flip-flops A and B and one input X. The circuit is described by the following flip-flop input equations:
JA = X'
KA = A
JB = B'
KB = X
(a) Drive the state equations A (t1 and B (t +1) by substituting the input equations for the J and K variables.
(b) Draw the state diagram of the circuit.
