Design of an Wide-band FIR filter with Sharp Transition using Generalized Sampling Kernels

This paper proposes a new design of a computationally efficient FIR filters with wide passband and sharp transition, where generalized sampling kernels are introduced and utilized along with the IFIR filter structure. In particular, the proposed filter design approach provides a closed-form solution for filter coefficients, yielding a practical design procedure for linear-phase sharp FIR digital filters with wide passband. Key-Words: wide-band FIR filters, sharp transition, linear-phase, IFIR structure, interpolation, sampling kernel
