Assignment 5
1) Analyze the synchronous sequential circuit given in the figure below by answering following questions:
a) Determine which model (Mealy or Moore) the circuit uses. Explain. (3 points)
b) Determine the expressions for the input functions that drive the J0, K0 , and D1 inputs of the flipflops. (12 points)
c) Determine the expressions for the next states Q0
+
and Q1
+
