FIR filter design using WINDOW FUNCTION

      This experiment was to design a linear phase FIR filter using window function. The filter parameters such as Passband frequency and Stopband frequency, attenuation in Passband and Stop band was mentioned by the user. Now depending on the value of As the window function is automatically selected in the program and executed. As we had kept the Stopband attenuation as 50dB the Hamming window function was used for execution. With an increase in the order, the number of lobes in the stop band also increases.

  1. Due to its linear phase there was no distortion in the output.

    1. The linear phase response is observed with Symmetric and Anti-symmetric H(n)

  2. Infinite signal can be truncated using Window Function.
