I want to have some kind of pluggable enumeration/discovery system similar to what i use for filters and drivers etc
<azonenberg>
but i think i will want to create gui dialogs
<azonenberg>
and have wizards you can use to specify configuration and format

[scopehal-apps] azonenberg de15eb4 - OscilloscopeWindow / Timeline: fixed bug where the first waveform added to a group would think the timebase was fs, causing MoveToBestGroup to make extra groups for no reason

but is there a simple closed form way to calculate insertion loss and phase of an RLC package model? in particular, series R - L between input and output
<azonenberg>
then C from output to ground
<azonenberg>
For the moment I'm only interested in S21 mag/angle
<someone-else>
azonenberg: calculate complex impedance of the RLC and the pkg pin's load (PCB trace Z0) and then do the usual voltage divider math?
<azonenberg>
This is the kind of thing that not having an EE degree makes difficult :P
<azonenberg>
I never actually did a lot of the intro calculus based circuit analysis classes and stuff
<someone-else>
I might be rusty on network theory, but I think it works like that
<someone-else>
basically keep the same math one uses for resistive circuits
<someone-else>
but replace all impedances with complex ones
<someone-else>
no calculus, just complex numbers

someone-else: "no calculus, just complex numbers" is a false dichotomy imo. i've always struggled with the complex impedances stuff because it was just a magic tool that worked for some unknown reason. without any gears in the model, how would i know when it is applicable?
<florolf>
the base reality is differential equations. what made this click for me was realizing that complex impedances are equivalent to what you get when you plug those differential equations into a laplace transform. and suddenly all the special cases for non-sinusoidal/periodic waveforms fall out implicitly.
<florolf>
maybe they tell you this when you take an EE course, but people seem to treat this as two different things when they are in fact the same
<someone-else>
florolf: I agree these two descriptions are mostly (or completely, depending on the definition) equivalent; what I meant is simple impedance calculations with complex numbers are just easier compared to doing the full calculus thing
<someone-else>
and complex numbers (at least in EE context) are just a convenient way to represent harmonic oscillators
