需要硬件支持才能当实际意义上的示波器用，但是模拟示波器的有matlab、LabVIEW等，可以直接测到声卡的波形。 -Hardware support to when the actual meaning of the oscilloscope, analog oscilloscope matlab, LabVIEW can directly measure the waveform of the sound card is required.

简易低频信号源设计，用来发出各种正弦波、三角波，等波形，实用-Simple low-frequency signal source design

绘制传输线方程的波形的gui界面，并且可以根据用户输入的参数绘制出史密斯圆图，计算阻抗匹配的条件。-Draw gui interface waveform transmission line equation, and can be drawn based on user input parameters of the Smith chart, impedance matching condition calculation.
