FIR filter design using Window function


FIR is Finite Impulse Response.In this experiment,we designed a linear phase FIR filter using scilab software and implemented. The attenuation in passband and stopband are provided as input and the magnitude response for high pass and low pass filter is plotted. The window function is selected depending on the value of attenuation in stop band.We used Hanning Window function in this experiment.

    Windowing method of FIR filter design is easy to understand

    There are different types of windows based upon the Passband Attenuation.They are Rectangular,Hamming,Hanning and Blackamnn.We selected the most suitable based on the Attenuation in passband

    Rectangular window is used for the smallest attenuation

    But we can't use this for narrowband filters

    As we go from rectangular window function to hanning window, we get smoother response which reduces Gibbs phenomenon.

    It is used where optimum response is needed
