So i am trying to calculate the fourier transform of this waveform. I have made an attempt at it but i dont think its right: S(t) = 1000t The integral of: 1000t*e^-jwt dt , with the limits: 0 to 1x10^-3

- Discrete-time Fourier transform. Language. Watch. Edit. In mathematics, the discrete-time Fourier transform (DTFT) is a form of Fourier analysis that is applicable to a sequence of values. The DTFT is often used to analyze samples of a continuous function.
- I wanted to calculate the Fourier transform of sin(at) and ended up that it‘s indeterminate. Wolfram Alpha says tho that the answer has to do with the Dirac delta function.
The Fourier descriptor method was chosen over other methods to describe the individual particles due to its flexibility and ease of use. It does not suffer from the re-entrant angle problem of the (R,0) Fourier method and accurate location of a centroid for each particle is not required.

Since the Fourier Transform or Discrete Fourier Transform is separable, two dimensional DFT can be decomposed to two one dimensional DFTs. Thus the computation of two dimensional DFT can achieved by applying one dimensional DFT to all rows of two dimensional complex matrix and then to all columns (or vice versa). Higher dimensional
- Hi Ken, you need to Add zero values at the end of the data sets to get data as 2^n for the extended period. While doing FFT the number of points are going to reduce by half comparing with Fourier ...
