FIR filter design using frequency sampling method

The aim of the experiment was to design digital filter using frequency sampling method. The magnitude and phase spectrum were plotted for LPF and HPF. 
It was observed that the phase plot is similar. Also, if the order of LPF and HPF are same, then the phase plot for both the filters is also same. The observed and calculated values of As and Ap were verified.

    Discontinuity is observed in phase plot between lobes and also when the phase spectrum goes out of the range of -pi to pi.

    Simplest method of filter design.

    FIR filters are designed using OAM or OSM method

    For any linear phase filter,we get output as delayed input.So output is not distorted

    Order can be decided the using adaptive technique by constantly checking the response

    This method requires less computation than windowing method.

    Frequency sampling realization is computationally more efficient than direct form realization
