信号波形参数自动观测方法研究

分别对《信号与系统》教材中的冲激函数和周期矩形脉冲的傅立叶级数两种波形进行了全面完整的编程，并经过反复上机调试，使波形准确地显示出来。而且能够生动形象地演示出信号波形参数变化对信号波形产生的影响。这无论是对教学还是科研都具有重要作用，可使学生们加深对理论知识的理解和掌握。

A Study in the Method of Automatic Observation for Signal Waveform Parameter

Using the Java language which is popular today and learned easily, I make a qualitative study about the parameter of the signal wavcform. Towards to the swash function and the Fourier array of the periodic rectangle pulse two kinds waveform in the signals and systems teaching material, I program completely for them respectively, and I tune them again and again by computer, making the waveforms shown out accurately. Furthermore, they can demonstrate the parameters changing influence on the signal waveforms vividly. This is very important effect for teaching and scientific research, and it can make students understand and administer the theoretical knowledge deeply.
