1, electronics and communication engineering. Electronic communication engineering is an engineering field that combines electronic science and technology with information technology to build a modern information society. The basic theory of electronic science and technology and information technology is used to solve technical problems in electronic components, integrated circuits, electronic control, instrumentation, computer design and manufacturing and related fields in electronics and communication engineering, and to study the theory and technology of detection, transmission, exchange, processing and display of electronic information.
2. Signal and information processing. Signal and information processing is a first-class discipline under the two disciplines of information and communication engineering. This subject focuses on signal and information processing, including information acquisition, conversion, storage, transmission, exchange and signal and information processing in applications. It is an important part of information science, and its main theories and methods have been widely used in various fields of information science.
