What does 'FM' stand for on the end of a radio station?

Answer 1

"FM" stands for "Frequency Modulation" one of the principal ways (along with Amplitude Modulation [AM], and Phase Modulation [PM]) of impressing a signal (such as audio) on a radio carrier so that it can be transmitted over the air.

Answer 2

In general, FM radio refers to radio that is broadcast using FM, or frequency modulation, as its modulation scheme. Frequency modulation is the shifting of the frequency of the transmitted signal above and below an assigned "center frequency" or "carrier frequency" to impress the signal on the carrier. This modulation scheme is resistant to noise to a much greater degree than amplitude modulated (AM) signals. Sometimes we talk about FM radio as those broadcast frequencies between about 88 MHz and 108 MHz on the electromagnetic spectrum. This is often what the term means, but as FM is a way to put information on a carrier, that type of modulation could be used on just about any signal you'd care to apply it to. Certainly communications and amateur radio use it frequently on frequencies outside the so-called FM broadcast band. To make it simple there is an AC signal of fixed frequency and level at the transmitter and that is transmitted to the air. that is a carrier signal wich has no information but the radio station modulate this Carrier by an analog sound voice which makes the frequency change and a radio will detect this frequency change and extract back to analog signal regenerating the analog signal voice.

Answer 3

There is something wrong with your receiver. ( and usually FM sets particularily for stereo have far higher quality control than say pocket transister portables. the sound component of old-style Television broadcasts, is in the FM oir frequency modulation band. obviously the visual component requires TV components!

Answer 4

It's a commercial or educational station that broadcasts

on a carrier frequency between 88 and 108 MHz.

Answer 5

"FM" = "Frequency modulation"

That's the term for one method of adding information to the radio waves.

There are several other methods.
