An Efficient Method for Narrowband FIR Filter Desing

GORDANA JOVANOVIC DOLECEK, ARTURO SARMIENTO REYES

Resumen


A NEW EFFICENT METHOD FOR IMPLEMENTING NAROWBAND FIR FILTERS IS PRESENTED. THE METHOD IS BASED ON AN INTERPOLATED FILTER (FIR) STRUCTURE AND A CASCADE OF COMB AND INTEGRATOR (CIC) STRUCTURES. THE NOVELTY OF THIS TECHNIQUE IS THAT THE CIC STRUCTURE IS USED AS AN IMAGE SUPPRESOR IN AN IFIR STRUCTURE. THE METHOD IS USEFUL FOR NARROWBAND FIR FILTER DESIGN AND SOME DESIGN EXAMPLES FOR LOWPASS AND HIGHPASS FILTERS ARE GIVEN.
