“Digital Signal Processing” is a subject which studies mathematical methods for the digital processing of signals. It covers several mathematical methods for digital signal processing such as analog signal conversion, Fourier transform of signal, design of an infinite impulse response (IIR) digital filter, and design of a finite impulse response (FIR) digital filter.
In order to acquire application abilities of understanding the mathematical principles covered in the subject and of applying them to practice, students must develop the ability to convert various analog signals into digital ones and to send them to computers to analyze various kinds of information.
In order to solve this problem, Jong Kyong Su, a researcher at the Faculty of Communications, has employed LabVIEW in his teaching to enhance the abilities of cognition and creation.
First, he made his students active in acquiring mathematical knowledge in signal processing by planning his lectures so that students could develop a comprehensive DSP that covers all the contents of the lecture.
Second, he planned his lectures so that students could put their mathematical knowledge touched in lectures into use by using LabWIEW, thus raising their application ability.
Third, he led students to writing a comprehensive program that runs through the whole course from the subprograms prepared in each lecture, thus increasing the ability of students to apply their mathematical knowledge for digital signal processing.
In the lectures, he made students develop a comprehensive program using LabVIEW that enables digitization, communication, Fourier transform, digital filtering, and reproduction of audio signals to digitize analog signals for digital communication and to process digital signals.
The new teaching method helped raise enthusiasm for study and cognition effect of the students. The students could be able to have a good understanding of what they learnt and make simulations by themselves using LabVIEW.
