1. Design a combinational circuit with three inputs: r, y, = and
three outputs: A. B. C. such that,
- When the binary input xyz represents the decimal digits 1, 3, or
4, the binary output ABC should represent the decimal digit that is
3 greater than the input: that is 4,6 or 7 respectively.
- Similarly, when the binary input represents the digits O or 2,
the binary output should represent the digit that is 2 greater than
the input.
- The remaining three, binary representations of the decimal
digits 5, 6, and 7 never occur.
A ) Start by drawing the truth table for the functions A, B, and
C.
B) Next, using K-Maps find all minimal forms of the three
functions.
C) Finally, draw a circuit with three inputs and three outputs,
representing a minimal form of the functions.
