Digitalization is a process that consists of converting continuous analog signals into a finite number of discrete states. The digital electronics or digital electronic circuits are an interesting part of the whole domain. The numbers and words are good examples for digital information; we can manipulate them only by techniques of digital electronics. The digital electronics represent more advantages compared to analog circuits, for example, the digital signals can be transmitted due to noise, so there is no degradation.
The information storage is much easier with the digital systems, what is another advantage. There are some disadvantages too compared to analog electronics. Sometimes, for the same works, the digital electronics use more energy that the analog ones, and many times, the digital ones are more expensive. Logic gates are often used for constructing digital circuits; with this we can make combinational logic, what is important in this field. The transistors are also elementary in digital electronics’ field.
