What is a top hat function?
[1] The Top Hat Transform function is a grey-level image analysis tool that allows extracting peaks and valleys in a non-uniform background. This function can be applied onto a grey-level Digital Elevation Model (DEM).
What is the Fourier transform of Signum function?
The signum function does not satisfy the Dirichlet conditions, and therefore, strictly speaking, it does not have a Fourier transform. Fourier transform of signum function can be obtained by taking a limit on G(f) for a to approach to zero. speaking, they do not have Fourier transform.
What is the Fourier transform of Dirac function?
The Fourier transform of a function (for example, a function of time or space) provides a way to analyse the function in terms of its sinusoidal components of different wavelengths. The function itself is a sum of such components. The Dirac delta function is a highly localized function which is zero almost everywhere.
Which function Cannot be expanded as Fourier series?
So, x(t) is a periodic or not periodic. Since function in (b) is non periodic. So does not satisfy Dirichlet conditionand cannot be expanded in Fourier series.
