1. Show the logic circuit implementation of the state machine described by the state diagram below. In each state, the two-bit value on the first line is the state, and the one-bit value on the bottom is the output. Start with the truth tables, and then show the complete logic circuit. Just use a box to represent a flip-flop. Don't draw all the logic on the inside. 00 01 10

4. Two multiplexers are connected as shown below. The inputs (A, B, C) and the output F are 4-bits and (D and E) are one-bit. The numbers inside the multiplexers correspond to the value of the selectors D and E which will decide which input A, B or C will pass to the output F (For example, If D = 0 and E = 0 then C will be selected to pass to F). C 0 0 B 1 A D E Write a VHDL description of the circuit.
