<p dir="auto">Now I use scipy.signal intensively for my research. And I miss some functions, which are necessary for my research. Hence I coded it myself. I use these functions to observe attributes of digital filters, which I designed. Therefore I saved them in a file and called it designtools.py. I tried to code it in scipy-style and tested it for many types of filter. Following is the list of functions</p>
<p dir="auto">find, rem (I copied from matplotlib), phase, phasejumb, firtype, zerophase, groupdelay, smithdelay, sphakdelay, cplxpair, cplxreal, zpk2sos, tf2sos, sos2zpk, sos2tf</p>
<p dir="auto">For more information see also documentation in the code.</p>
