What is the syllabus for the postgraduate entrance examination in electronic information engineering of Huazhong University of Science and Technology?
I am in China for science and telecommunications.

Specialized courses are generally about signals and systems. We studied Oppenheimer's textbook, which is as thick as bricks. This book is recommended for reviewing specialized courses. This book is used for the examination in our department.

If it is a postgraduate entrance examination in a foreign school, it is necessary to start preparing early. If the score is not high, it will be dangerous. There are not many students enrolled in this department.

Math and professional courses will be easy to get high.

In 2009, the outline of postgraduate entrance examination for signal major courses is as follows. If it is a 20 10 postgraduate entrance examination, you can refer to it.

Overview of 824 "Signal and Linear System"

The first part of the exam instructions

I. Nature of the examination

The national postgraduate entrance examination is designed for colleges and universities to recruit graduate students. Among them, "signal and linear system" is unified. Its evaluation standard is the passing level or above that excellent undergraduate graduates can reach, so as to ensure that the admitted students have the basic professional level, which is conducive to the preferential admission of colleges and universities.

The examination object is the candidates who took the 2009 national postgraduate entrance examination.
