pic related. It's actually far simpler than it seems.

the frequency is increased to transmit a 1 and decreased to transmit a 0

your radio listens to the signal, detects shifts in frequency, and converts it to a digital signal

That's interesting, but how did radios work in the time before binary?

>>7917554
That's actually only for "HD Radio"

traditional FM and DM don't use 1s and 0s

>>7917593
AM & FM

Guess I'll read up on it. Does XM function in binary?

>>7917615
XM is satellite "HD" radio, and is digital.

This guy doesn't know anything. Signal analysis is far from simple.

We aren't talking about signal analysis.

Producing an AM signal is actually pretty simple. A child could build an AM transmitter as a science fair project.

nice harmonics n shiet

>>7917698
Signal analysis may be hard for an electronic engineer, but anyone with even slight training in maths will find it incredibly easy.

It's fourier transforms, op.

simple in 2D maybe

>>7918981
2D > 3D

Radios still work the same way they did 100 years ago. Rather than having 2 levels, one for 0 and the other for 1, you transmit on all the frequencies inbetween to make an analog audio signal. The receiver then just has to amplify it and put it through a speaker.

1. Take a signal
2. Multiply it by a sine with a much higher frequency
3. You now have a signal modulated by a carrier wave
