Right.
Let me add that this isn't just about modems, though perhaps their case is the most familiar one.

Aside, watching the spectrum of a telegraphy channel over time is rather instructive, even on a plain vanilla oscilloscope.
At low transmission rates, of course, otherwise it's just a blur.
With a teletype providing a soundtrack.

Naturally, watching any spectrum is very instructive.
(It is not for nothing that good spectrum analyzers are expensive.)
These days, there ought to be plenty of video recordings, but it hadn't occurred to me to look for them.

I don't know whether the strict definition of _baud_ should be about symbols per second or state changes per second.
I suppose it might depend on the layer of abstraction of the Discourse.

_________
Exploring phase modulation, pulse code modulation, and then the interesting types of modulation etc. (whose names I forget) is left as an exercise for the proverbial reader thirsting for knowledge.
Warning: it is a rabbit cave, not merely a hole, with multiple branches connected to other large rabbit caves.
But you would be in the good company of giants.

The other is a Raspberry Pi image for the same purpose: connect a paddle or straight key to GPIO, audio out to a speaker, boot it, and you are live on the #CW server.

You can leave it on and hear people calling CQ or testing their hardware.

I managed to get my SO as a learning partner, he says it's having fun! (And learning at a faster pace than me ^•^')
