In this paper, we present a comparative simulation study of three denoising algorithms using wavelets. The denoising algorithms (i.e., universal threshold, minimax threshold and rigorous SURE threshold) have been used to remove white Gaussian noise f

The design of analog filters is a well established theory. However, in spite of the great variety of filter types available (Butterworth, Chebyshev, elliptic, etc), there are some other less known filter types, such as monotonic L filters, Halpern, a
