1. Inputs
BIT1: Bit
BIT2: Bit
INP: Bit
2. Outputs
OUT0 Bit
OUT1 Bit
OUT2 Bit
OUT3 Bit
3. Implementation
The output bits are set as follows:
If BIT1 = 0 and BIT2 = 0 and INP = 1 then OUT0 = 1,
else OUT0 = 0
If BIT1 = 1 and BIT2 = 0 and INP = 1 then OUT1 = 1,
else OUT1 = 0
If BIT1 = 0 and BIT2 = 1 and INP = 1 then OUT2 = 1,
else OUT2 = 0
If BIT1 = 1 and BIT2 = 1 and INP = 1 then OUT3 = 1,
else OUT3 = 0
