2. Design a sequential network state diagram for a 2-bit counter (four states) with one input X, and two outputs Z2, Z1. When input x = 0, the state of the circuit remains the same. When X = 1, the circuit goes to the next state: from 00 to 01, from 01 to 10, from 10 to 11, or from 11 to 00. The Z1, Z2 represent the value of the counter. Assume q0 = 00, 91 = 01, q2 = 10, and q3 = 11. 3. Complete below table according to the SN state diagram you drew in #2. y2 yi Z2 Z1 Y2 Y1 0 0 1 olololo 0 1 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1
