Variable Frequency Oscillator — (VFO) (engl: Oszillator mit veränderbarer Frequenz) ist der Oberbegriff für alle abstimmbaren Oszillatorschaltungen oder Frequenzgeneratoren. Im Regelfall wird entweder der Kondensator oder die Induktivität eines Schwingkreises geändert. VFO… … Deutsch 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 Frequency Oscillation Generator — n. audio oscillator invented by William R. Hewlett in which the frequency of the oscillations produced can be varied continuously … English contemporary dictionary
Clapp oscillator — The Clapp oscillator is one of several types of electronic oscillator constructed from a transistor (or vacuum tube) and a positive feedback network, using the combination of an inductance (L) with a capacitor (C) for frequency determination,… … Wikipedia
Colpitts oscillator — Early schematic of a Colpitts circuit, using a vacuum tube, redrawn from the patent publication. A Colpitts oscillator, invented in 1920 by American engineer Edwin H. Colpitts, is one of a number of designs for electron … Wikipedia
Crystal oscillator — A miniature 4 MHz quartz crystal enclosed in a hermetically sealed HC 49/US package, used as the resonator in a crystal oscillator. A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal … Wikipedia
RC oscillator — Electronic oscillators are often designed around an LC tank circuit, a tuned circuit formed with an inductor and a capacitor. But use of an inductor is not a requirement. Instead, the tuned circuit can be built using just resistors and capacitors … Wikipedia
Parametric oscillator — A parametric oscillator is a simple harmonic oscillator whose parameters (its resonance frequency omega and damping eta) vary in time in a defined wayAnother intuitive way of understanding a parametric oscillator is as follows: a parametric… … Wikipedia
Microelectromechanical system oscillator — Microelectromechanical system (MEMS) oscillators are timing devices that generate highly stable reference frequencies. These reference frequencies are used to sequence electronic systems, manage data transfer, define radio frequencies, and… … Wikipedia
Hartley oscillator — The Hartley oscillator is an LC electronic oscillator that derives its feedback from a tapped coil in parallel with a capacitor (the tank circuit ). Although there is no requirement for there to be mutual coupling between the two coil segments,… … Wikipedia
