一维FDTD仿真传输线理论，分别设定了不同的电源电阻和负载电阻，并且可以自动生成.avi文件播放。(One-dimensional FDTD simulation of the transmission line theory, were set up different power resistance and load resistance, and can automatically generate .avi file playback.)

利用双线性变换法，设计一个0.4dB截止频率为10kHz且在30kHz处有最小阻带衰减为50dB的数字巴特沃兹低通滤波器，其抽样率为100kHz。利用教材（4.35）式求解原型模拟滤波器的阶数，并利用Matlab的M文件buttap设计模拟原型滤波器。用M文件bilinear将模拟滤波器传输函数变换成期望的数字传输函数。请用Matlab画出其增益和相位响应，并给出设计的具体步骤。(fuck!!!)
