%% Design an FIR Interpolator % To design an FIR Interpolator using the |designMultirateFIR| function, % you must specify the interpolation factor of interest (usually greater % than 1) and a decimation factor equal to 1. % You can use the default half-polyphase length of 12 and the default % stopband attenuation of 80 dB. Alternately, you can also specify the % half-polyphase length and stopband attenuation values. % % Design an FIR interpolator with interpolation factor set to 5. % Use the default half-polyphase length of 12 and the default stopband % attenuation of 80 dB. b = designMultirateFIR(5,1); fvtool(b,'impulse')
