Design a system with the following state changes: this is a sequential circuit with three flip-flops. the state sequence is changed with a clock as in the order of, 111, 010, 100,110, 001, 011, 101, 000, 111 and repeat. use jk flip-flops.

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
