Digital system, also known as digital systems, the use of separation (ie, discontinuous) values (0 or 1) represents the information for input, processing, transmission, storage and so on. Relatively non-digital (analog) systems use a consecutive range of representatives of the information. Although digital representations are separate, but representative of the information can be separated (eg numbers, letters, etc.), or continuous (such as sound, images and other measurements of continuous systems.) Digital representation is usually used in computer science and electronics, in particular real-world information is converted into binary digital form, such as digital audio and digital photos. The signal carrying data in electronic or optical pulse, the amplitude of each represents a logic 1 (with pulse and / or high) or a logical 0 (no pulse and / or low).

Digital Technology
Digital technology (digital tech) Introduction Digital technology also known as digital technology, because its core is to a series of consecutive digital information, or is not continuous. In electronic technology, is passed, the signal processing and handling can be divided into two categories: one signal is analog signal, such signal characteristics, regardless of time or from signals from the size are continuously changing, for transmission, processing and analog signal processing technology called simulation technology; the other signals are digital signals, digital signals are characterized, in terms of time or size are discrete, or that are not continuous, transmission, processing and handling of digital signals is called digital technology. Comparison with simulation technology Compared with analog technology, digital technology has the following features: (1) digital technology in general are binary, so all elements have two stable states can be used to represent binary, (such as "high" and "Low"): 0,1. So the basic unit circuit is simple, the components of the circuit is not very stringent accuracy requirements, allows the device to have a greater dispersion parameters, as long as you can distinguish between two distinct states. The characteristics of digital integrated circuits is very beneficial. (2) anti-jamming, high precision. As digital technology transfer process and dealing with binary information, less susceptible to outside interference, and thus anti-interference ability. In addition, it can be used to increase the number of binary digital to improve accuracy. (3) to facilitate long-term storage of digital signals, so a lot of valuable information resources can be preserved. (4) confidentiality, and digital technology can be encrypted so that some valuable information resources can not easily be stolen. (5) versatility, standard logic components can be used to form a variety of digital systems. As digital technology has the above characteristics, developed very rapidly, so in the electronic digital computer, numerical control technology, communications equipment, digital meters, and other sectors of the national economy have been more widely used.
