MATLABtf函数 Tf函数用来建立实部或复数传递函数模型或将状态方程、或零级增益模型转化成传递函数形式。 sys=tf(num,den)命令可以建立一个传递函数,其中分子和分母分别为num和den。输出sys是储存传递函数数据的传递函数目标。 单输入单输出情况下,num和den是s的递减幂级数构成的实数或复数行向量。这两个向量并不要求...

Use tf to create real-valued or complex-valued transfer function models, or to convert dynamic system models to transfer function form.

This MATLAB function returns the vector of numerator coefficients, B, and the vector of denominators, A, for the equivalent transfer function corresponding to the notch filter.
