Hello

Please draw the circuit clear and the example are given below

Page 1. A circuit has four inputs D, C, B, A encoded in 8421 natural binary form. The inputs in the range 0000 0 to 10112 1 represent the months of the year from January (0) to December (11). Inputs in the range 1100 to I111 (i.e., 12 to 15) cannot occur or don't care. The output of the circuit is a logical one if the month represented by the input has 31 days. Otherwise the output is false. The output for inputs in the range 1100 to 1111 is undefined. a) Draw a truth table to represent the problem and use it to construct a K- map b) While plotting, include those can't occur (X)s literals on K-Map as well. While grouping, consider adjacent (X) as many as needed along with (l) to have largest group. You can't just have a group with only (CX) but you can include as many as needed along with (1). c) Use the K-map to obtain a simplified expression for the function. d) Construct a circuit to implement the function using NOR gates only.
