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.
ReplyDeleteSimplest method of filter design.
ReplyDeleteFIR filters are designed using OAM or OSM method
ReplyDeleteFor any linear phase filter,we get output as delayed input.So output is not distorted
ReplyDeleteOrder can be decided the using adaptive technique by constantly checking the response
ReplyDeleteThis method requires less computation than windowing method.
ReplyDeleteFSM method is more efficient

ReplyDeleteFrequency sampling realization is computationally more efficient than direct form realization
