The direction is the same, the tutor is different, and the exam subjects are the same.
Initial test:
Take two exams: communication principle and signal and system.
Communication Principle was edited by Cao Lina of Xidian.
Signals and systems use higher education edition.
"Signals and Systems" has a tutorial book compiled by a teacher and published by Xidian. Look at that.
Communication principle, see the papers of previous years.
It is best to take remedial classes for professional courses.
Re-inspection:
Professional written test+English listening+English interview+professional interview
Professional written test:
Take an examination of DSP, analog electricity (both high and low), digital electricity, microcomputer principle 16 (8-bit single chip microcomputer also has it), and information theory (Shannon) seems to be these.
English listening refers to CET-6.
An English interview is to introduce yourself and then have a simple conversation.
Professional interviews will generally ask you about your graduation design, as well as simple communication principles and knowledge of various circuits.
Just ask Xidian for re-examination reference materials.
