Variable-frequency drive — A variable frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor.cite book | first=Sylvester J. |… … Wikipedia
Frequency distribution — In statistics, a frequency distribution is an arrangement of the values that one or more variables take in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and… … Wikipedia
Frequency-hopping spread spectrum — (FHSS) is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. A spread spectrum transmission offers three main advantages over… … Wikipedia
Frequency-Agile Solar Radiotelescope — (FASR) is a next generation radio telescope for solar observation in radio and microwave frequency range.On contrary to other general purpose radio telescopes such as VLA, FASR is specifically designed for solar observation. Compared with other… … Wikipedia
Variable capacitor — Rotary variable capacitor A variable capacitor (also known as a variable air condenser ) is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C… … Wikipedia
Variable-frequency oscillator — A variable frequency oscillator (VFO) in electronics is a oscillator with an oscillation frequency that can be electronically changed (hence, variable).cite book |title=The ARRL Handbook for Radio Amateurs, Sixty Eighth Edition |editor=Larry D.… … Wikipedia
Variable fractional delay filter — Introduction= One important advantage of the variable digital filter is that the frequency characteristics, including the magnitude response and the phase response are tunable without re implementation of the filter. Variable fractional delay… … Wikipedia
Variable frequency transformer — A variable frequency transformer is used to transmit electricity between two asynchronous alternating current domains. The VFT is a relatively recent development (first deployed in 2004). Most grid interties use high voltage direct current… … Wikipedia
Variable Specific Impulse Magnetoplasma Rocket — Artist s impression of several VASIMR engines propelling a craft through space The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is an electro magnetic thruster for spacecraft propulsion. It uses radio waves to ionize and heat a… … Wikipedia
Variable speed air compressor — A Variable Speed Drive (VSD) Air Compressor [ [http://www.quincycompressor.com/qgv.html Variable Speed Drive Compressor] ] is an air compressor that takes advantage of Variable Speed Drive technology. This type of compressor uses a special drive… … Wikipedia
Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… … Wikipedia
