We designed linear phase FIR filter using frequency sampling method using scilab. The magnitude response was plotted. It was observed if filter order increases ,number of lobes in stop band also increases. We observed that phase is linear and similar to LPF and HPF if order is kept same. If phase is linear output will not be distorted.
FSM method is more efficient
ReplyDeleteyes because many of the input values become zero
DeleteEasy to Implement.

DeleteFSM is more efficient than Window method

DeleteFor any linear phase filter,we get output as delayed input.So output is not distorted
ReplyDeleteFIR filter requires higher order.
ReplyDeleteFrequency sampling realization is computationally more efficient than direct form realization
