fm
Definition
- Noun:
- Fermium: A radioactive, synthetic, metallic chemical element (symbol Fm) with atomic number 100. It is produced artificially, for example by bombarding plutonium with neutrons.
- Frequency Modulation: A method of encoding an audio signal onto a radio carrier wave by varying its instantaneous frequency. This is the standard technique for high-fidelity radio broadcasting.
Usage Examples
- Noun (Fermium):
- The element fm was first discovered in the debris of a thermonuclear explosion.
- Scientists produced a few atoms of fm in the laboratory for study.
- Noun (Frequency Modulation):
- This radio station broadcasts in FM, so the sound quality is very clear.
- Most music stations use FM transmission.
Advanced Usage
- "FM band": Refers to the range of radio frequencies (usually 88 to 108 MHz) allocated for FM broadcasting.
- I scanned the FM band to find a good station.
- "FM synthesis": A method of sound synthesis where the timbre of a simple waveform is changed by modulating its frequency with another waveform.
- Early digital synthesizers often used FM synthesis.
Variants and Related Words
- AM/FM: A common descriptor for radios capable of receiving both Amplitude Modulation and Frequency Modulation broadcasts.
- The clock radio has an AM/FM tuner.
- Fermium-257: A specific, relatively stable isotope of the element fermium.
Synonyms
- For Frequency Modulation: There is no direct single-word synonym. It can be described as "frequency-modulated broadcasting" or contrasted with "AM" (Amplitude Modulation).
- For Fermium: There are no synonyms, as it is a unique element name. It can be referred to by its symbol "Fm" or atomic number "element 100".
Related Phrases
- "On FM": Used to specify that something is being broadcast via frequency modulation.
- You can hear the game on FM 102.5.
- "FM radio": A device for receiving FM broadcasts, or the system/service itself.
- I listen to the news on FM radio every morning.
Noun
-
a radioactive transuranic metallic element produced by bombarding plutonium with neutrons
-
modulation of the frequency of the (radio) carrier wave
