Frequency sampling method allows us to design FIR filter for standard frequency selective filters such as lowpass, highpass, bandpass, etc. filters with arbitrary frequency resopnse.In this experiment, we designed an FIR filter using Frequency Sampling method for low pass and high filters.
We took the input specifications similar to the expt performed using Window method. We observed that as the order increases the, the number of lobes in the stop band increases.The major advantage of FSM lies in the efficient frequency-sampling structure which is obtained when most of the frequency samples are zero.

Elaborate more on how you performed this experiment
ReplyDeleteCan we do the same experiment for the Bandpass filter and Bandstop filter?
ReplyDeleteYes,sure. We will have to make some additions in the code accordingly.
DeleteFor BPF/BSF we need to define desired frequency response of the filter we want to design.
DeleteNeed to think the criteria to find order of filter.
ReplyDeleteThe concept of Frequency sampling method is explained well but as Nivedita said you should elaborate the procedure.
