sos2zpk(sos)
The number of zeros and poles returned will be n_sections * 2
even if some of these are (effectively) zero.
Array of second-order filter coefficients, must have shape (n_sections, 6)
. See sosfilt
for the SOS filter format specification.
Zeros of the transfer function.
Poles of the transfer function.
System gain.
Return zeros, poles, and gain of a series of second-order sections

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
