Characteristics of digital electronic technology
trait
1, which has both arithmetic and logical operations. Based on binary logic algebra, digital circuits use binary digital signals, which can perform not only arithmetic operations, but also logical operations (AND, OR, NOT, judgment, comparison, processing, etc. ) is convenient, so it is extremely suitable for operation, comparison, storage, transmission, control, decision-making and other applications.
2. Simple implementation and reliable system. Digital logic circuit based on binary has strong reliability. The small fluctuation of power supply voltage has no influence on it, and the influence of temperature and process deviation on its reliability is far less than that of analog circuit.
3. High integration and simple function realization. High integration, small size and low power consumption are one of the outstanding advantages of digital circuits. Circuit design, maintenance and maintenance are flexible and convenient. With the rapid development of integrated circuit technology, the integration of digital logic circuits is getting higher and higher. With the development of small-scale integrated circuits (SSI), medium-scale integrated circuits (MSI), large-scale integrated circuits (LSI) and very large-scale integrated circuits (VLSI), the functions of integrated circuit blocks have also risen from component level, device level, component level and board level to system level. The design and composition of the circuit only need to be connected by some standard integrated circuit block units. For non-standard special circuits, programmable logic array circuits can also be used to realize any logic function through programming.
