Hi,
I was wondering if anyone might know what the analytic Fourier transform of a Super-Gaussian is?
cheers

A supergaussian function is a mathematical function that decays faster than a Gaussian function. It is also known as a hypergaussian function and is commonly used in signal processing and image processing.
The Fourier transform of a supergaussian is a complex-valued function that represents the frequency components of the original supergaussian function. It is a useful tool for analyzing signals and understanding their frequency content.
The Fourier transform of a supergaussian can be calculated using the Fourier transform formula, which involves integrating the product of the supergaussian function and the complex exponential function. Alternatively, it can also be calculated using fast Fourier transform algorithms for faster computation.
The Fourier transform of a supergaussian has numerous applications in signal and image processing, such as image denoising, feature extraction, and image enhancement. It is also used in optics, quantum mechanics, and other areas of physics and engineering.
One limitation of using the Fourier transform of a supergaussian is that it is not defined for all supergaussian functions. Additionally, the Fourier transform does not preserve all information about the original function, so some information may be lost in the transformation process. Finally, the Fourier transform may be computationally expensive for large datasets, requiring advanced algorithms for efficient computation.
