What's am and FM mean on the radio?
When you tune into the radio you'll hear signals from many different stations. At least part of each station's signal is in amplitude modulation (AM), while another portion is in frequency modulation (FM). The sound is different in each, and a radio will only tune in to one or the other depending on the frequency setting you choose.
What does am and FM mean on the radio?
Short for amplitude modulation, or AM, amplitude is the strength of the signal that a radio station broadcasts. It’s most commonly used for traditional radio broadcasting, and the station’s signal strength is represented by the number of the dial on your radio. A higher number means a stronger signal.
What does am and FM mean on the radio station?
The “am” (for amplitude modulation) refers to the strength of the signal. It’s the maximum level of radio waves that the station can send through the air. It’s also the most commonly used power setting for radio stations. And the “FM” (frequency modulation) refers to the frequency at which the station broadcasts. You can find it with a radio dial on most radios.
What does am mean on the radio?
If an AM radio station is broadcasting on a frequency of 5,000,000 Hz, then it is playing at a frequency of 5,000,000 cycles per second. “AM” is an acronym for amplitude modulation, a type of radio transmission where the strength of the signal fluctuates in response to the sound being sent. A station that uses AM as its primary method of transmission is called a “mono” station.
What do am and FM mean on the station?
There are two different types of radio stations in the United States: AM and FM. They sound different and cover different frequencies. An AM station broadcasts on a very low frequency, around the area of 500 kilocycles, which is also the frequency of your car radio. It’s called amplitude modulation. FM radio covers the high end of the spectrum, around 100 MHz, and it’s called frequency modulation. It allows for more channels to be closer together, so you can get a
