Super-Gaussian window function and its applications

Describes a new window function which is called Super-Gaussian window function. The most simple window function is rectangular window, it causes sharp discontinuities at the window edges and gives rise to the ringing in the transform. On the other hand, one can use an artificial window function with rounded corners that gradually reduces the function to zero at the endpoints. The details of the characteristics of the Super-Gaussian (SG) window function and some applications are discussed. It is shown that the SG function is a very good window function and easy to use.<>
