1. Design a combinational circuit that takes four inputs (E (the enable), A, B, and C), has four outputs (X, Y, Z, and EoS (the end of Sequence flag)) and meets the following specifications. 1. If ABC = 111 then, regardless of the value of E, the end of sequence flag EoS = 1 else EoS = 0. 2. If E' 1 then XYZ = ABC. 3. If E' = 0 and ABC # 111 then XYZ should be set to the code following the value of ABC in this list: 000, 100, 101, 001, 011, 010, 110, 111. For example, if ABC = 010 then XYZ = 110. This is a type of Gray code sequence (A Gray code is an encoding of numbers so that adjacent numbers have a single digit differing by 1) 4. If E' = 0 and ABC = 111, then XYZ may be set to anything (this is called a "don't care" and should be represented in the truth tables and K-maps with an X.) Draw a truth table (with the operands in this order E', A, B, C, X, Y, Z, EOS) for this combinational circuit's function. a.

1. Design a combinational circuit that takes four inputs (Ē (the enable), A, B, and C), has four outputs (X, Y, Z, and EoS (the end of Sequence flag)) and meets the following specifications. 1. If ABC = 111 then, regardless of the value of E, the end of sequence flag EoS = 1 else EoS = 0. 2. If E' = 1 then XYZ = ABC. 3. If E' = 0 and ABC ‡ 111 then XYZ should be set to the code following the value of ABC in this list: 000, 100, 101, 001, 011, 010, 110, 111. For example, if ABC = 010 then XYZ = 110.
