由于数字信号处理(digital signal processing)的领域中,我们处理的信号都是经过采样(sampling)的,而这些信号的采样点数是有限的。因此离散Fourier变换是一个有限维内积空间里的基变换。我们设信号采样的数量为N,则我们的信号向量 x\in\mathbb{C}^N 。在离散场景下我们定义信号(时域下的)自然基: \mathbf{\hat{e}...

This paper describes the software implementation of the 1D and 2D Fast Fourier Transform (FFT) on the DSP 96002 digital signal processor. Two real-valued programs based on FFT packing and real-valued FFT algorithm are introduced. A novel pipeline extension technique is introduced to eliminate the...

MATLAB function is designed to facilitate signal processing using the Fast Fourier Transform (FFT). The function follows a step-by-step approach, generating an original signal, applying specific frequency band filters using Butterworth filters, and visualizing the results in both time and frequency ...
