That's part of what makes Fourier wonderful. "Nonetheless, for some signal-processing applications, banded matrices could prove more efficient than the Fourier transform."
那是傅里叶变换美妙的部分，但对于某些信号处理应用来说，带状矩阵可以比傅里叶变换更加高效。

One of the most common digital-signal-processing techniques is the discrete Fourier transform (DFT), which breaks a signal into its component frequencies and can be represented as a matrix.
最常见的数字信号处理技术之一是离散傅立叶变换（DFT），它把一个信号分解成它的组成频率，并表示成一个矩阵。
