FIR FILTER DESIGN USING WINDOWING METHOD

    The aim of the experiment was to design digital filter using windowing method and study the spectrum. The input parameters were passband attenuation(Ap), stopband attenuation(As), passband frequency(Fp), stopband frequency(Fs) and sampling frequency(F). The magnitude and phase spectrum for LPF and BPF using Hanning window were plotted. 
    The observed and calculated values of Ap and As were compared. Thus, the values were verified. The phase spectrum was observed to be linear.

    The trick is to select the window function that will give a filter with the correct transition width and attenuation in stopband.

    Blackman window is the best since it is used when the stop band attenuation is highest

    There are other window functions also

    Rectangular window has less value of As i.e. 29

    Hanning window provides stop band attenuation of 44db where as Blackman window provides highest attenuation of 74db
