Why is FM radio more popular?
FM broadcasting is capable of higher fidelity—that is, more accurate reproduction of the original program sound—than other broadcasting technologies, such as AM broadcasting. Therefore, FM is used for most broadcasts of music or general audio (in the audio spectrum).
Why is FM better than AM and PM?
FM (or PM) transmitters are more complex than AM because the variation of modulating signal has to be converted and detected from the corresponding variation in frequencies. 12. AM receivers are very less susceptible to noise because noise affects the amplitude, which is where information is stored in AM signals.
Why is AM radio still around?
One reason AM broadcast is still around it is used mostly for talk radio. There are a few FM talk radio stations, most are on AM. Talk radio does not require the quality of audio that FM can provide with music, so many AM stations went with talk radio. Talk radio has really saved AM.
What’s the difference between AM and FM radio stations?
Most of the widely-listened radio stations, at least in the US, are on AM. AM signals travel much further than FM (and not everyone pays for satellite), so if you’re out in the middle of nowhere, AM is pretty much it unless you’re streaming something from a device.
What is FM radio and how does it work?
FM radio is a form of broadcasting transmission based on “frequency modulation.” With frequency modulation, it’s possible to impress audio signals into a radio-frequency carrier wave and maintain a high quality of sound.
What kind of music did local radio stations play?
Local stations often carried their own programs featuring the popular music of the area. Stations such as Nashville, Tennessee’s WSM played early country, blues, and folk artists. The history of this station illustrates the ways in which radio—and its wide range of broadcasting—created new perspectives on American culture.
