WebTwo of the 10 filter functions are simply wrappers around the scipy.signal function signal.firwin () for designing filters of a specific order when one (lowpass) or two (bandpass) critical frequencies are given. The wrapper functions fix the window type to the firwin default of hann (hanning). The remamining eight are described below in Table 1.
