DigitalSignal Processing (DSP) is a professional basic course for electronic information science. Its basic concepts and basic analysis methods have penetrated into information and communication engineering, circuits and systems, integrated circuit engineering, biomedical engineering, physical electronics, navigation, guidance and control, electromagnetic field and microwave technology, underwater acoustic engineering, electrical engineering, power engineering, aeronautical engineering, environmental engineering and other fields.
It is the use of computer or general (special) signal processing equipment, the use of numerical calculation method to process the signal of a discipline, including filtering, transformation, compression, expansion, enhancement, recovery, estimation, identification, analysis, synthesis and other processing, in order to extract useful information, easy to apply the purpose.
Compared with analog signal processing, digital signal processing has many advantages such as high flexibility, high precision, high stability, and ease of large-scale integration. With the emergence and rapid development of VLSI, it has developed and improved rapidly in theory and application, replacing traditional analog signal processing methods in many application fields. It also opens up many new application fields.
New algorithms, new realization technologies, high-speed devices, multi-dimensional processing and new applications based on high-speed digital computers and VLSI have become the development direction and research hotspot of DSP. Due to the wide range of DSP applications (such as voice, biomedical engineering, acoustics, radar, earthquake, communication, remote sensing and telemetry, etc.), a large number of high-quality DSP research and development talents are needed in various fields, so the digital signal processing course has been highly valued by academia and colleges and universities, and has reached a high level of development and gradual improvement.
