ABSTRACT
Mathematical transformations are applied to signals to obtain further information from the signal that is not readily available in the raw signal. By applying the various transformations available today, the frequency information in these signals is obtained. There are many transforms that are used quite often by engineers and mathematician’s. Hilbert transforms, short-time Fourier transforms, Radon transform, and the Wavelet transform constitute only a small portion of a huge list of transforms available at engineer’s and mathematician’s disposal where each transformation technique has its own area of application, advantages and disadvantages.
