我有一个离散系统,输入为x_n,输出为y_n现在我想计算这个系统的脉冲响应,也就是我想找到系统的输出输入为[1,0,...,0]。 对于我的例子:
x_n
y_n
[1,0,...,0]
x_n = [0,1,2,3,4,5,6,7];然后y_n = [0,0.1,0.3,0.5,0.4,0.7,0.3,0.5];
x_n = [0,1,2,3,4,5,6,7];
y_n = [0,0.1,0.3,0.5,0.4,0.7,0.3,0.5];
我已经尝试过:(我不确定这是否正确)
X = fft(x_n); Y = fft(y_n); Impulse_response = ifft(Y/X);
还有其他方法可以找到脉冲响应吗?
