When ftype=high, the function button obtains the numerator polynomial coefficient (b) and denominator polynomial coefficient (a) of BW high pass filter When ftype=stop, the function button obtains the numerator polynomial coefficient (b) and denominator polynomial coefficient (a) of BW band stop filter When the filter is designed as low-pass or band-pass filter, this parameter can be defaulted. 'ftype' indicates the type of filter to be designed. The numerator polynomial coefficient (b) and denominator polynomial coefficient (a) of BW filter are obtained by using the function button. The parameter N returned by the function button is the order of the filter, and wc is the 3dB cut-off frequency of BW filter.

The input parameters wp and ws (rad/s) of the function button represent the passband and stopband cutoff of the filter respectively, and Ap and As (DB) represent the passband and stopband attenuation of the filter‘ S' indicates that the designed filter is an analog filter. Butterworth analog filter =buttord(wp,ws,Ap,As,'s') Common function formats are as follows: 1.
