A digital system has four one?bit inputs D, C, B, A, and an output F. The input represents a 4?bit number in the range 0 to 15, where A denotes the least?significant bit. The output F is true if the binary input is divisible by 3, 4, or 7. Construct a truth table to represent this system and construct a logic circuit to implement it.
