ESE218 Test 3 Name______________________________ ID___________________ Problem 1 (10 points). Design a 2-bit binary counter with saturation: the outputs should go through the sequence 0-1-2-3-3-3.…with input X =0 (up) and 3-2-1-0-0-0… with X =1 (down). The circuit should be of synchronous type, it should be based on D-flip-flops, and flip-flops outputs Q 1 Q 0 should serve as outputs of the circuit. Assume the initial state is Q 1 Q 0 = 00. 1. Construct a state diagram and state table 2. Derive excitation equations for the flip-flop inputs 3. Draw the circuit diagram.

2 Problem 2 (10 points). Design a single-mode synchronous binary counter with outputs going through the sequence 0-1-2-3-4-5-. . and repeat (6 states). The circuit should use T-flip-flops; the flip- flop output should serve as outputs of the circuit. Assume flip-flops are cleared initially. 1. Construct a state diagram and state table 2. Derive excitation equations for the flip-flop inputs 3. Draw the circuit diagram.
