Mind your I’s and Q’s: The Basics of I/Q data

Understanding in-phase and quadrature components using a phase modulation example

I/Q data appears in many data science settings: RF (radio frequency) data, timeseries analysis, audio processing, and more.

Plus, one of my favorite geometric demonstrations is the decomposition of an angle-modulated sinusoid into two orthogonal, amplitude-modulated sinusoids. As a teaser of what’s to come…

As a motivation, I’m going to use a radio example. From ham radio to …
