Digital system design

Definition

Digital system design refers to the process of creating digital circuits that process and store information using binary values (0s and 1s). This design process involves understanding the various components such as flip-flops, logic gates, and state machines, and how they interact to perform specific tasks. A significant aspect of this field includes designing reliable systems that can handle data efficiently, especially through the use of sequential circuits like flip-flops.
