To add, digital signals aren't decoded either, they're also demodulated. Digital information is encoded in some form (or sometimes left as is), then modulated for broadcast, then demodulated, and lastly decoded. The encoding can give the data signal more favorable properties for the modulation that is to follow.

Put into consideration on how during WWII when 700 AM WLW (Cincinnati, Ohio) was broadcasting on an outstanding 500 KW of power, at which the entire world could hear the local news as well as keep the troops updated on the wartime news to the point that Hitler himself called the station a nuisance. Fortunately for anyone who would care enough, there's a video on here where a guy walks around the station and shows the massive retired all-tube transmitter, water cooling system, transmission antenna, and power transformers for the old 500 KW setup.

Trust me when I say that while this is a good high level overview... the actual math behind AM and FM can be a bit mind boggling. Learning digital modulation techniques now and to start we covered AM/FM. Trying to find the frequency spectrum of an FM signal of a certain data signal and carrier frequency is a pain in the butt. The practical solutions that we learned still only estimate it (carson's rule, bessel functions...etc). Additionally, one might be interested in knowing that FM itself is only a type of angle modulation, one can also instantaneously vary the phase of a carrier signal to represent data (PM), the result looking very similar to FM but tracking different data signal properties.

You can transmit and AM or an FM signal on basically any frequency. Broadcast bands have been established that places commercial AM broadcast on lower frequencies (535kHz to 1700 kHz) and places commercial FM broadcast on a higher frequency band (87.5 Mhz to 108 Mhz). With the right equipment you could easily transmit an AM signal inside of the commercial FM broadcast band (87.5 Mhz to 108 Mhz). I have a transceiver at home that allows me to transmit AM at 144Mhz or FM at 28Mhz. AM and FM are modes, bands and frequencies are different.

Thanks for the flashbacks to my signals processing course linus. I really needed a good dose of not knowing what is going on.

Also, FM is actually a subcategory under something called Angle Modulation. Angle Modulation consists of Phase Modulation (PM) and Frequency Modulation (FM). This is because in application they are varying the angle in a cosine function. Thus the name: Angle Modulation. FM actually changes the frequency, but when you add an angle in the cosine function, we call that the phase modulation, and pretty much just shifts a signal left and right (hence the name Phase Modulation).

AM and FM have nothing to do with wavelength... they are just modulation types. FM broadcast band is typically 88-108 Mhz while AM broadcast is 540 Khz to 1700 Khz in the US. This is often called Medium frequency band. Medium frequency can bounce off the ionosphere at night. FM broadcast is in the VHF band and is typically line of sight. There is cases where you can here it for long distances. Tropospheric ducting and bouncing off the ionosphere called e-skip. These effects however are very rare and uncommon.

The way I'm interpreting his video is that when you tune your radio receiver to a certain station, your tuning to the carrier wave frequency. The carrier wave is just that , a "carrier". The stuff you want to listen to (also a analog signal) is superimposed with the carrier wave, then off they go into the wild blue yonder. Your radio receiver's antenna will pick up the signal, as you are tuned to the carrier frequency (if I' m interpreting his video correctly) .

One thing I found weird with fms is if you’re listening to 99.5 fm (for example), and you switch to 99.4 or 99.6 you can still hear the same station as 99.5 although you can hear some static. I live in India and here we have more fm stations compared to am. I listened to both fm and am and I find that in am volume goes up and down and in fm I can hear static sometimes.

I love to dx AM radio at night. The furthest station I've picked up was AM 870, WWL out of New Orleans, which traveled almost 1900 miles. AM 1040 WHO is a common station here too, which is roughly 1500 miles away. DXing is so fun. Its the thrill of finding that long distant radio station, way, way out their. You need a good AM radio though, with a good AM antenna. I never have tried, but the "graveyard" frequency's are a jumbled mess, but there are people who try ( and successfully catch ) distant radio stations in the rumbling audio.

+linustechtips IT IS NOT as simple as a couple of wires!!!! Tuner circuits are beautiful LCR circuits. When you turn a knob, you rotate plates which change the common area between parallel plates, thus changing the capacitance(C). This in-turn changes the resonant frequency of the circuit(because resonant frequency omega=1/root(LC).

+Kaushik Harith It is also possible to make an AM radio using only a variable coil, instead of a fixed coil and variable capacitor. In fact, most older car radios used variable coils, known as "slug tuning".

vwestlife Interesting! How would one change the no of turns of the coil/length of coil/Area of cross section? Those are the factors that magnetic field depends on and hence Inductance(because L is flux per unit induced current.). I can't picture any easy or efficient way of doing so. The only easy way would be to change the permiability, but that would limit you to using two frequencies.

Kaushik Harith The physical coil of wire stays the same. To tune it, you slide one coil in and out of another coil, or slide a metal slug in and out of the coil (hence the name "slug tuning").

vwestlife That is what I thought. But how would we get a continuous distribution of resonant frequencies?

I find analog technology, although technically inferior, way more fascinating than digital technology. It seems so much more difficult to get right that the fact that it can end up sounding or looking as good as digital is mind blowing.

Analog technology can be improved not so with digital. With digital there is a finite standard (1's and 0's) in order to change any quality a new "standard" must be developed. With analog things just get better with better components.

@@stephensnell5707 as analog devices get better, LESS interference or noise will happen, but in a digital world, everything is finite and requires a new "standard" to be compatible. You can improve analogy, but you cant improve digital

Perfect timing Linus, I'll take a final exam on next Sunday in computer communications where I studied this in depth.

I remember we moved cities from Melbourne to Brisbane 2000km away when I was a kid and I managed to just pick up my favourite AM station in Melbourne - 3XY Hot Hits 1422AM - at night with a really really big antenna.

Hey kiddo, you're not old. Your first computer was a AthlonFX.

DAB Radio As Fast As Possible!

Another note (years later): at night there are actually less ions in our atmosphere. The reason AM goes further at night is less interference from the sun which, during the day, easily overpowers our AM emitters

Excellent job, thanks!

my phone's loaded with music streaming apps but a lot of the time...I'm just listening to a local fm radio station on the next radio app that unlocks the fm chip in the phone :I

I'm also on Virgin Mobile (prepaid Sprint) I know most android phones outside the US have the fm tuner usable but it's locked away over here. Sprint lets their phones use it but with an app called Next Radio. Most there for sone added ad revenue though o_o
