Design of quadrature mirror filter bank using Lagrange multiplier method based on fractional derivative constraints
Fractional calculus has recently been identified as a very important mathematical tool in the field of signal processing. Digital filters designed by fractional derivatives give more accurate frequency response in the prescribed frequency region. Digital filters are most important part of multi-rate...
