Flip flop is sequential or combinational

WebIn a digital system, the logic circuits can be divided into two classes: combinational and sequential. A combinational circuit uses logic gates only; a sequential circuit uses flip-flops (ffs) and logic gates. The discussion of ffs is left to the next chapter. Most of the flip-flops are synchronous. Such a flip-flop has two sets of input—the ... WebJul 26, 2024 · The feedback path between combinational circuit and memory elements(flip-flops) in a sequential circuit can produce instability if the outputs of memory elements are changing while the outputs of the combinational that go to flip-flop inputs are being sampled by the clock pulse. I didn't understand this statement.
