Digital & Logic Design - Visual Learning Platform | Boolean Algebra, Logic Gates, Sequential Circuits

What is Digital & Logic Design?

Digital Logic Design is the foundation of all digital systems, dealing with the design and analysis of digital circuits using Boolean algebra and logic gates. It forms the basis for understanding how computers, processors, and digital devices operate at the hardware level.

Think of digital logic as the language that computers speak - a world of 0s and 1s where complex operations are built from simple logical operations. Every smartphone, computer, and digital device relies on the principles of digital logic design to function.
