In view of the concept abstraction in the teaching process of 'Communication Principle' and the difficulty of students understanding of the propagation process of signal in the channel, in order to intuitively show the change state of signal transmission in the channel, this paper takes the classical speech signal as the research object, and combines the key and difficult points in the teaching process to develop and design a set of demonstration experiment software based on MATLAB / App Designer. The article first introduces the basic principle and overall design scheme of speech signal transmission in the channel, and then carries out interface design, algorithm simulation function design and demonstration function design. The software integrates specific demonstration experiments into abstract theoretical teaching, which greatly improves the teaching effect, helps deepen students ' understanding of theoretical knowledge, helps teachers reduce the teaching difficulty of course teaching, and improves teaching efficiency.
