Digital electronics is the science of designing and building electronic circuits that can store, process, and communicate information. These circuits use discrete components, which are smaller than traditional components like resistors and capacitors, to achieve this. These discrete components are typically made of semiconductor materials.
The building blocks of digital circuits are logic gates. A logic gate is a simple electronic circuit that performs a specific operation on two or more input signals. These operations can include:
AND: The input signals are combined together and the output signal is equal to 1 only if both input signals are 1.
OR: The input signals are combined together and the output signal is equal to 1 if either input signal is 1.
NOT: The input signal is inverted and the output signal is equal to the input signal.
XOR: The input signals are combined together and the output signal is equal to 1 only if both input signals are different.
These logic gates can be combined together to create more complex circuits. For example, an AND gate can be used to combine two signals, while an OR gate can be used to combine three signals.
Digital electronics circuits are built using a combination of logic gates and other electronic components to perform specific functions. These circuits can be used for a wide variety of applications, including computers, communication systems, and medical devices
