WebWhat Is a FIR Filter? The use of FIR filters (or finite impulse response filters) has grown in popularity in the live sound world as digital signal processing (DSP) for loudspeakers becomes more and more sophisticated. While not a new technology in itself, these filters provide a powerful tool in system optimization due to their linear phase ... WebImpulse Response (FIR) and Infinite Impulse Response (IIR) filters [6]. Although IIR filters are faster and have fewer components compared to FIR filters, they should be tested for stability per each design changes. On the other hand, FIR filter is stable by definition and has linear phase response.

"WebAug 11, 2006 · Note that this is really independent of the sampling rate because it expresses length in terms of time. Where the sampling rate comes in is when it's chosen and directly affects the number of samples in the filter impulse response. For the same situation, choosing FS=1kHz, fs=400Hz and fp= 300Hz: N = FS/ (fs - fp) = 1000/ (100) = 10 So, it ... " - Fir filter single echo
