Transmission of information in ANY form can be done digitally or analoguely.
Beginning about 30 years ago, everything slowly started changing to digital. Today, all commercial satellite communication, all optical fiber communication, all internet communication, all computer communication, all commercial cable communication, all commercial television, and much of the telephone system, are all digital.
On your computer ... .pdf, .jpg, .mp3 etc. are all digital methods of moving and storing information.
AM and FM radio are an interesting subject. They're all still analog. They could easily be changed to all digital, and it would be a big improvement, both for the broadcasters and for the listeners. BUT ... every AM and FM radio that anybody has now would be obsolete. Every single radio would either need to be replaced, OR you'd need to add a digital decoder to every radio, like we had to do with our TV sets a few years ago when television suddenly became all digital. With AM and FM radios, the decoders would be bigger, and would cost more, than most of the radios.
And that's why commercial radio broadcasting is still analog.
Analogue signals transmit information for such things as <em><u>AM/FM radio</u></em>.
<h3><u>Explanation</u>;</h3>
<em><u>Analogue transmission is a method of transmission that involves conveying voice, data, image, signal or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of the variable.</u></em>
<em><u>An analog signal differs from a digital signal in that in a digital signal the continuous quantity is a representation of a sequence of discrete values. Digital signals must have finite set of possible valu</u></em>es.
<u><em>Am or FM radi</em></u>o information are transmitted using analogue signals
