发明傅里叶变换和拉普拉斯变换的人真乃鬼才 这是我看到过对他们讲解最清晰的视频: What does the Laplace Transform really tell us? A visual explanation (plus applications)The intuition behind Fourier and…

Having introduced the concept of the Fourier series in section 4.3, we will now introduce the Fourier transform. You will recall that the Fourier series is the representation of a function as a finite series of sine and cosine terms. If you look back at the definition of the individual terms...

In this paper, we propose some new result in n-dimensional Laplace transforms involved with Fourier cosine transform; these results provide few algorithms for evaluating some n-dimensional Laplace transform pairs. In addition, some examples are also presented, which explain the useful applications of ...

In most applications, the z-transform is somewhat easier to work with than the DFT because it does not require the use of complex numbers directly. The z-transform plays a similar role for digital signals as the Laplace transform does for the analysis of continuous signals. If a discrete ...
