The relationship between the continuous signal spectrum and the discrete signal spectrum is the one of the important and difficult points in “Digital Signal Processing”course and “Signals and Systems”course. In this paper, the transformation process from the continuous signals into the discrete signal was analyzed. And on this basis, the relationship between the continuous signal spectrum and the discrete signal spectrum was deduced, which reduce the difficulty of understanding of students and improve the quality of teaching, so good teaching effect was achieved.
