1. Consider a 2-bit counter with an active-high enable (E) that counts in the following sequence: 00, 01, 11, 10, 00, 01,... There are 4 states, so 2 FFs needed to implement the counter. a. Draw the state diagram for this counter. b. Create a table of the inputs, present states, next states, and the required inputs for a D- FF implementation (inputs: D1 & D0, outputs: Q1 & Q0). The table will be similar to the tables on slides 20 and 14. c. Determine the minimized combinational logic expressions to create the inputs to the D-FFs.
