由于医学信号的随机性、广泛性和复杂性，使得生物医学信号处理课程的教学具有一定的挑战。为了提高教学效果，本文结合实际的教学过程，探讨了关于该课程实验演示软件制作的思路、方法、目的，指出如何把医学信号处理中抽象的算法用演示工具直观的表达出来-Because the randomness of medical signals, breadth and complexity, making biomedical signal processing teaching has certain challenges. In order to improve teaching effectiveness, this paper, the actual teaching process, the course of experiments on the production of presentation software ideas, methods, purpose, point out how the medical signal processing algorithms in the abstract presentation tool used to express the intuitive
