Scenario: Consider the following sequential circuit:
X and Y are the two points showing state of above circuit. The presence and absence of current at the given points identify the following states:
q0(X=0, Y=0) = (0,0)
q1 (X=0, Y=1) = (0,1)
q2 (X=1, Y=0) = (1,0)
q3 (X=1, Y=1) = (1,1)
Questions:
a. Write down the expressions to find out new X, new Y and Output?
[Marks 5]
b. Calculate all the values of the respective transition table for a mealy machine?
[Marks 10]
c. Draw the resulting mealy machine from the transition table (calculated in step b)? [Marks 5]
