说明：  Script for designing FIR filter low pass with lineal phase & cut-frecuency equal to obtained from a IRR Filter. Windows used: a)Rectangular window. b)Hamming window. c)Kaiser window. "Calculus of the windows are obtained from commands hamming, boxcar & kaiser." Magnitude and frecuency response of the FIR filter are generated for each window tecnhique applied.
