摘要
Teaching process can be seen as the information transmitted from the teacher to the student. In the teaching process of principle of airborne electronic equipment, many signals and signal processing methods are involved. Understanding these signals and signal processing methods is the key of grasping the principle of airborne electronic equipment. In the teaching procedure of airborne electronic equipment, to get a better expression of signals and signal processing methods, signal visualization method is presented making the information transferring process intuitively and easy to understand. In the proposed method, signal visualization includes two sides: signal character visualization and signal processing visualization. Signal character visualization is making the signal character of time domain, frequency domain, energy domain and spatial domain visualized. Signal processing visualization is making signal procedure including filter, modulation, demodulation, transform visualized. Finally, the application of this method used in communication principle teaching shows the good result.
