The frequency-response masking (FRM) approach was introduced as a means of generating narrow transition band linear-phase FIR filters with a low arithmetic complexity. This paper proposes an approach for synthesizing two-channel maximally decimated FIR filter banks utilizing the FRM technique. Compared to conventional quadrature-mirror filter (QMF) banks, the proposed banks lower significantly ...

There is a serious lack of empirical studies on Islamic banking. This paper attempts to fill that gap to some extent. Using data for the 1990-98 period, several hypotheses and common perceptions about the practice of Islamic banking have been tested. The performance of Islamic banks has been evaluated using both trend and ratio analyses. For this purpose, some objective “benchmarks” for various...

The concept of cyclic filter banks was introduced independently in Ref. [1] and [2], though in [1], a different nomenclature was used. “Cyclic filter banks” is a superset of the traditional non-cyclic filter banks, and readily suggest implementation of subband filtering through DFT. In this paper we show that the DFT implementation is also advantageous for the conventional FIR filter banks. The...
