Logic Gates Explained

Understanding logic gates is essential for grasping how digital circuits function. Each AND gate requires all inputs to be one for the output to be one, while OR gates need only one input to be one for a positive output. The discussion then shifts to adders, which not only add numbers but can also perform subtraction through clever manipulation of bits. A one-bit full adder is introduced, highlighting its three inputs and the concept of carrying over from previous calculations.
