Digital FIR Filters Without Tears

Designing and Implementing Non-Recursive Filters for DSP; New Low-Power Multipliers and Multiplier/Accumulators Speed Filter Design

Digital filters once required specialized design techniques, high-performance costly hardware, and complicated software to implement; for these reasons, they found only restricted application. Today, in sharp contrast, the availability of low-cost high-speed digital signal-processing ICs, such as multipliers and multiplier/accumulators, combined with easy-to-use standardized design procedures, has dramatically simplified filter implementation. Read full article
