Abstract :
In this work, a design method for narrow-band and wide-band frequency-response masking FIR filters is proposed. As opposed to most previous works, the design method is not based on a periodic model filter. Instead, the masking filter is designed for a given stopband edge. The model filter design is based on optimizing the sparseness of the filter, and, hence, the resulting model filter is not required to be periodic.
