New American Oxford Dictionary
frequency
fre quen cy |ˈfrēkwənsē ˈfrikwənsi | ▶noun ( pl. frequencies ) 1 the rate at which something occurs or is repeated over a particular period of time or in a given sample: shops have closed with increasing frequency during the period. • the fact of being frequent or happening often. • Statistics the ratio of the number of actual to possible occurrences of an event. • Statistics the (relative ) number of times something occurs in a given sample. 2 the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves ), or in an electromagnetic field (as in radio waves and light ), usually measured per second. (Symbol: f or ν ) • the particular waveband at which a radio station or other system broadcasts or transmits signals. ORIGIN mid 16th cent. (gradually superseding late Middle English frequence; originally denoting a gathering of people ): from Latin frequentia, from frequens, frequent- ‘crowded, frequent. ’
frequency distribution
fre quen cy dis tri bu tion ▶noun Statistics a mathematical function showing the number of instances in which a variable takes each of its possible values.
frequency division multiplexing
fre quen cy di vi sion mul ti plex ing ▶noun Telecommunications a technique for sending two or more signals over the same telephone line, radio channel, or other medium. Each signal is transmitted as a unique range of frequencies within the bandwidth of the channel as a whole, enabling several signals to be transmitted simultaneously. Compare with time division multiplexing.
frequency modulation
fre quen cy mod u la tion (abbr.: FM ) ▶noun the modulation of a radio or other wave by variation of its frequency, esp. to carry an audio signal. Often contrasted with amplitude modulation.
frequency response
fre quen cy re sponse ▶noun Electronics the dependence on signal frequency of the output –input ratio of an amplifier or other device.
Oxford Dictionary
frequency
fre |quency |ˈfriːkw (ə )nsi | ▶noun ( pl. frequencies ) 1 [ mass noun ] the rate at which something occurs over a particular period of time or in a given sample: an increase in the frequency of accidents due to increased overtime. • the fact or state of being frequent or happening often. 2 the rate per second of a vibration constituting a wave, either in a material (as in sound waves ), or in an electromagnetic field (as in radio waves and light ): different thicknesses of glass will absorb different frequencies of sound. (Symbol: f or ν ) • the particular waveband at which radio signals are broadcast or transmitted. ORIGIN mid 16th cent. (gradually superseding late Middle English frequence; originally denoting a gathering of people ): from Latin frequentia, from frequens, frequent- ‘crowded, frequent ’.
