Out of the two method which can be used to design FIR filter, here we have used the second method i.e Frequency Sampling Method. It is the most simplest and direct technique to design an FIR filter for getting the desired frequency response. In this method we simply sample the desired frequency response and perform an IDFT in order to obtain the corresponding FIR.
In this experiment a Scilab code was written to perform the operations.

good!
ReplyDeleteThank you.
DeleteIt is one of the easier approaches.It is to be used when we are already aware of the frequency response graph.
ReplyDeleteShort and descriptive!
ReplyDeleteHowever, has time aliasing effects if under sampled
ReplyDeleteYes undersampling causes time aliasing effects
ReplyDeleteFSM is more efficient than Window method
ReplyDeleteSampling frequency must be at least twice the max frequency
ReplyDeleteFsm us an easy method
ReplyDeleteFSM is computationally more efficient.
