Digital electronics is the branch of electronics that deals with systems that represent information in discrete states using binary code. It is responsible for electronic systems where information is encoded as "1"s and "0"s. Digital electronics has evolved rapidly and made more complex systems possible through the integration of components. Digital systems can be classified as wired systems like combinational or sequential systems, memories, and converters. Programmed systems include microprocessors and microcontrollers. Digital electronics has achieved great importance as it is used to create robots and forms the foundation of computer systems. It is advancing technologies like information technology, mechatronics, and medical applications.
