FIR filter coefficient generation is a critical task that provides essential support for DSP software programming. The process involves multiple steps including filter design and parameter calculation, covering aspects such as filter type selection, cutoff frequency determination, and window function choice. Proper coefficient generation enables effective signal filtering and frequency response adjustment to meet various application requirements. From a code implementation perspective, this typically involves using mathematical algorithms like the windowing method or frequency sampling method, where key functions may include calculating ideal impulse responses and applying window functions to reduce spectral leakage. The generated coefficients are often stored in arrays for real-time processing in DSP architectures.
