FREQUENCY-RESPONSE MASKING BASED FILTERS WITH THE EVEN-LENGTH BANDEDGE SHAPING FILTER

摘要

This paper presents the design of Frequency Response Masking (FRM) filter using an even-length filter as bandedge shaping filter. The optimization of each subfilter is carried out with the help of the Sequential Quadratic Programming (SQP) technique. It is shown, by means of examples, that the proposed FRM filters with even-length bandedge shaping filter leads to designs comparable to the original FRM filters.
