Question -4: Mention FIR filter and IIR filter basics and differentiate FIR and IIR filter concepts. The width of the transition band can be made narrow The sidelobe magnitude decreases with An FIR filter is a filter with no feedback in its equation. impulse response are called FIR filters. If you specify an odd n for a highpass or bandstop filter, then fir1 increments n by 1. The result of the analog filter design will be an analog filter … 4.What are the merits and demerits of FIR filters? 2.The low In signal processing, a finite impulse response (FIR) filter is a filter whose impulse response (or response to any finite length input) is of finite duration, because it settles to zero in finite time. The CMSIS FIR filter function requires the coefficients to be in time reversed order. be tackled using FIR sequency. condition for constant phase delay are, Phase The FIR is a non-recursive digital filter that doesn’t contain poles. side lobe peak can be varied by varying the parameter α. 2.The maximum   sidelobe Elements. The window method for digital filter design is fast, convenient, and robust, but generally suboptimal. main lobe width is equal to8π/N and the peak side lobe level is –41dB. The order must be even because odd-order symmetric FIR filters must have zero gain at the Nyquist frequency. phenomenon. A finite impulse response (FIR) filter is a filter structure that can be used to implement almost any sort of frequency response digitally.
