An AM is a member of the Welsh Assembly. AM is an abbreviation for `assembly member'. Am. is a written abbreviation for American. am WEAK STRONGAm is the first person singular of the present tense of be. Am is often shortened to 'm in spoken English. The negative forms are `I am not' and `I'm not'. In questions and tags in spoken English, these are usually changed to `aren't I'. Armenia (in Internet addresses). The symbol for the element americium. Amos. First person singular present indicative of be. the first person singular of the present tense of the verb be. in full amplitude modulation Variation of the amplitude of a carrier wave (commonly a radio wave) in correspondence to fluctuations in the audio or video signal being transmitted. AM is the oldest method of broadcasting radio programs. Commercial AM stations operate in the frequency range of 535 to 1605 kHz. Because radio waves of these frequencies are reflected back to the Earth's surface by the ionosphere, they can be detected by receivers hundreds of miles away. In addition to commercial radio broadcasting, AM is also employed in short-wave radio broadcasts, and in transmitting the video portion of television programs. See also FM
Amplitude modulation; a method of broadcasting in which the desired audio or video signal modulates the amplitude of a 'carrier' signal Analog Information that is reproduced using a continuously varying electronic signal
Amplitude Modulation, as employed in AM radio broadcast This modulation varies a carrier signal's amplitude or magnitude to encode it with the desired broadcast signal The encoded signal is then broadcast at the station's designated carrier frequency A radio receiver detecting that signal demodulates it or separates the desired modulation component from the carrier
amplitude modulation A modulation technique by which information is conveyed through the amplitude of the carrier signal Compare with FM and PAM See also modulation
Amplitude Modulation AM is the standard broadcast transmission system used by the majority of licensed radio stations The term is commonly used to differentiate between AM and FM radio
Amplitude modulation A method of operation for transmitting signals by radio waves, used in medium wave broadcasting
Short for Amplitude Modulation, an AM radio in R/C is considered a "budget" radio, what most newcomers to R/C will start out with Most hobbyists will be fine with an AM radio, but some racers can benefit from FM or PCM radios An AM radio will have more glitching than these other, more expensive, radios
a radioactive transuranic metallic element; discovered by bombarding uranium with helium atoms
Stands for 'Amplitude Modulation'   It is a radio broadcasting system in which the amplitude of the radio wave is modulated to produce the broadcast   It is generally mono (as opposed to FM's stereo), and consequently is used mainly by 'talk radio' formats   AM radio signals travel further than FM, and consequently, can be broadcast over greater distances with less power
Amplitude Modulation Modulation technique whereby information is conveyed through the amplitude of the carrier signal Compare with FM and PAM See also modulation
A modulation technique used to add information to a sine-wave signal; the magnitude of the sine wave, or carrier, is modified in accordance with the information to be transmitted
