摘要
以傅里叶变换为基础的传统技术所提供的频率分辨率是非常有限的,而基于有理传递函数模型的技术则可以提供更高的频率分辨率。有理传递函数模型比较适合在连续频谱条件下建模,而对于离散频谱,则采用谐波模型更加合适。
The frequency resolution provided by the traditional Fourier transform-based technology is very limited,but the technology on the basis of rational transfer function model can provide us with a higher frequency resolution.Rational transfer function model is suitable for modeling in the condition of continuous spectrum,and harmonic model is more suitable for modeling the discrete spectrum.
