Question

Using three rising-edge-triggered T flip-flops and a minumum number of additional gates, construct a circuit that will operate as a binary counter with an enable signal E. When E = 1, the counter should increment from 0 to 7 on each clock pulse, with (flip-flop outputs Q2Q1Q0 = 000- 001-010-011-100-101-110-111) and then roll over to 000 and repeat the sequence. When E=0, the counter should stop and hold its current count.

Note: (not modulo-8, but modulo-6: 000-001-010-011-100-101-000- ... )
