Aplikasi Tnterface Sptools Matlab Dalam Mendesain IIR Dan FIR Digital Filter

Abstract

This paper discusses examples of lowpass,highpass and bandpass filter digital designs by using a variet of filter design algorithm are available in Matlab for both IIR and FIR filter. Matlab provides diffirent options for digital filter design,which include function call to filter algorithm and a graphical user interface called Sptools Interfacing.Interface Sptools (Signal procesing tools) has more user friendly environment,more quicker display and simpler option than the option of making calls to the filter algorithms. However, the shortcoming of sptools is that it only displays magnitude response of the filter, not the phase response.
