Design of Orthogonal Wavelet Filters with Minimum RMS Bandwidth Using A Symbolic Approach

Filterbanks have many applications. The orthogonal wavelet filter is widely used in filterbank design because of its advantage in energy preservation. In this work, the orthogonal wavelet filter with a given length and a prescribed number of Vanishing Moment (VM) is designed to achieve minimum Root- Mean-Square (RMS) bandwidth by using a symbolic approach.
