What Is The Principle Of Designing Fir Filter Using Frequency Samplin

1.	What Is The Principle Of Designing Fir Filter Using Frequency Sampling Method?
Answer» In FREQUENCY sampling method the desired magnitude response is sampled and a linear PHASE response is specified .The SAMPLES of desired frequency response are identified as DFT coefficients. The FILTER coefficients are then DETERMINED as the IDFT of this set of samples.
