lp2lp_zpk(z, p, k, wo=1.0)
Return an analog low-pass filter with cutoff frequency :None:None:`wo` from an analog low-pass filter prototype with unity cutoff frequency, using zeros, poles, and gain ('zpk') representation.
This is derived from the s-plane substitution
$$s \rightarrow \frac{s}{\omega_0}$$Zeros of the analog filter transfer function.
Poles of the analog filter transfer function.
System gain of the analog filter transfer function.
Desired cutoff, as angular frequency (e.g., rad/s). Defaults to no change.
Zeros of the transformed low-pass filter transfer function.
Poles of the transformed low-pass filter transfer function.
System gain of the transformed low-pass filter.
Transform a lowpass filter prototype to a different frequency.

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
