What Are the Different Types of Digital Processing?

Digital signal refers to a signal whose independent variable is discrete and the dependent variable is also discrete. The independent variable of this signal is represented by an integer, and the dependent variable is represented by one of a finite number. In computers, the size of a digital signal is often represented by a finite number of binary numbers.

The advantages of digital signals are many. First of all, its ability to resist interference is particularly strong. It can be used not only for communication technology but also for information processing technology.

Digital signal processor is a professional signal processing equipment. It sends the collected raw data signals to a digital signal processor. Through signal filtering, sampling processing and digital signal transmission, the signal conversion is realized according to actual needs. This signal processing technology is widely used in medical and health, automation engineering, radar detection, aerospace and other fields. In the continuous development of science and technology, digital signal technology has been favored by enterprises. Its core products and technologies play an irreplaceable role in electronic information engineering. ^[3]

Digital signal characteristics

Digital signal processing technology extracts signal data, filters out valid information and invalid information, and finally converts the valid information into a more suitable signal form, making the signal more stable and accurate. The previous technology mainly used analog signals, but this method made it difficult to modify data parameters and the signal sensitivity was not high. In digital signal technology, binary logic technology is used. The technology has strong perception and adaptability to changes in sound, temperature and color. Better signal input and output. ^[3]

Digital signal advantages

Large scope of application: Digital signal processing technology is widely used in various fields and has a wide applicability. Digital signal processing technology can be applied in many fields, because there are many types of digital signal processors, which can be used by various software, and can also be selected according to different needs. When the operator stores data in the digital processing system, they can easily convert various information processing into the required form. Take computer network technology as an example. In the computer, digital signals can be used as the technology of the modulation processor. , Apply digital signal processing technology to program programming.

Fast processing speed: Compared with analog signal processors, digital signal processors have obvious advantages in high-speed processing. The digital signal simulator has a chip that is different from other chips. It mainly uses a Harvard structure. Professionals in electronic engineering can separate digital information programs and storage space to ensure that they do not interfere with each other and form a digital signal processor. Workflow. Comparing digital signal processing systems with traditional signal processing, digital signals can be used to identify and process other instructions during processing, which greatly improves the efficiency and speed of information processing. ^[3]
