Sequential circuit a There are two types of sequential circuits Synchronous(latch mode) sequential circuit: the behavior can be defined from knowledge of its signal at discrete instants of time. This type of circuits achieves synchronization by using a timing signal called the clock Asynchronous(fundamental mode) sequential circuit: the behavior is dependent on the order of input signal changes over continuous time, and output can change at any time(clockless)Sequential Circuit ◼ There are two types of sequential circuits: ➢ Synchronous (latch mode) sequential circuit: the behavior can be defined from knowledge of its signal at discrete instants of time.
