Question
Gray code numbering changes only a single bit from the previous number. For instance, the 3-bit gray codes are 000, 001, 011, 010, 110, 111, 101, 100, where the next value after the last value cycles back to the first value. Gray code can make efficient counters as fewer bit values change, resulting in less power being dissipated. Design a circuit that at each rising clock edge changes according to the 3-bit gray number pattern. (a) Complete the following truth table that shows the next state.
