How does 1 tiny radio frequency carry such a dynamic range of sounds to my receiver?
Also how is analog sound different from DAB?
>>7917486
amplitude modulation
or
frequency modulation
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

>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.
>>7917507
nice harmonics n shiet
>>7917507
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
