Intermediate Topic 18 of 51 Computer Architecture & Logic
Sequential Circuits
Circuits whose outputs depend on current inputs and stored state.
How it works
Outputs depend on inputs and stored state; they have feedback and clocked memory. Moore machine outputs depend only on state, Mealy outputs also on inputs.
Where it is used
Counters, controllers, traffic-light logic.
Common pitfall
Uninitialized state; always provide reset.
Where it fits in the course
Sequential Circuits is topic 18 of 51 in Computer Architecture & Logic, rated Intermediate. It follows Fetch-Decode-Execute Cycle. The next topic is Finite State Machines in Hardware.
