Just like IIR filter we have another digital filter called FIR which is Finite Impulse Response filter. The response to this filter is finite.
This experiment was performed on Scilab, just like IIR filter design experiment with different formulae for calculation.
When we are designing any filter a specific algorithm is dedicated to it. We followed the algorithm for FIR filter design, generated its code on Scilab and implemented. This method involves obtaining the finite response by using a windowing function. Hanning Window function was used here.

Rectangular window is generally not used because value of As=21dB
ReplyDeleteFIR filter poles are always only at the origin hence FIR filters are always stable.
ReplyDeleteRectangular window function is simple
ReplyDeleteScilab is used instead of MATLAB as it is an open source software.
ReplyDeleteThe appropriate window was selected according to the As value.
ReplyDeletewhat window function did you use?
