Compared with other majors, it is more difficult, mainly depending on the requirements of the school you apply for. But in fact, as long as students learn basic courses well, especially advanced mathematics, circuit principle, analog electronic technology and so on, it is not difficult to learn electronic information.

947 electronic information specialty includes two courses: signal and system and digital electronic technology. Candidates are required to master the basic knowledge of signal and system and digital circuit, including: the concept of signal and system, time domain analysis of continuous-time system, Fourier transform, Laplace transform and time domain analysis and Z domain analysis of discrete-time system; Expression and simplification of logic algebra, principle and application of logic gate circuit, analysis and design of combinational logic circuit, analysis and design of sequential logic circuit, generation and shaping of pulse waveform.
