Question: Find a function to detect an error in the representation of a decimal digit in Binary Code Decimal (BCD). In other words, write an equation

  1. Find a function to detect an error in the representation of a decimal digit in Binary Code Decimal (BCD). In other words, write an equation with value 1 when the inputs are any one of the six unused bit combinations in the, BCD code, and value O otherwise. (Hints: In BCD representation, every decimal digit is represented as follows: 0 - 0000, 1 - 0001, 2 - 0010, 3 - 0011, 4 - 0100, 5 - 0101, 6 - 0110, 7 - 0111, 8 -1000, 9 - 1001).
  2. Suppose that we have three binary variables X, Y, and Z for a full adder circuit. Y and Z are added by considering X as the previous carry. Variables S and C are used to store the resultant sum and the carry. Write down the truth table for the full adder circuit.
  3. Draw the full adder circuit in (b)esing a 3-to-8 line decoder and two OR gates
