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 of O through 15, where A denotes the least-significant bit. The output Fis 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.
