DSPP EXPERIMENT NO. 07

Digital FIR Filter Design using Windowing Method

A linear phase finite impulse response(FIR) filter was designed using Scilab. Filters like stop band and pass band attenuation and stop band and pass band frequency are taken as input from the user.There are different window functions that can be used like Hamming Window, Bartlet Window, Hanning Window, Blackman Window,etc. The window function used in this experiment is Hanning window.the formula is input in the Scilab code and then the program is executed

    Requires more computation

    Rectangular window function is simple

    Blackman window increase efficiency but requires higher order

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

    Window functions can be changed according to the requirements.

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

    FIR filter is designed by truncating infinite samples of hd[n] by using window function. Examples of window function are rectangular, barnet hamming, hanning and blackman

    window selection is done upon requirement of passband attenuation
