Wien bridge oscillator — A Wien bridge oscillator is a type of electronic oscillator that generates sine waves without having any input source. It can output a large range of frequencies. The bridge comprises four resistors and two capacitors. The circuit is based on a… … Wikipedia
Bridge circuit — A bridge circuit is a type of electrical circuit in which the current in a conductor splits into two parallel paths and then recombines into a single conductor, thereby enclosing a loop. It was originally used for measurement purposes, but can… … Wikipedia
Max Wien — (German pronunciation: [ˈviːn]; 1866 – 1938) was a German physicist and the director of the Institute of Physics at the University of Jena. He was born in Königsberg, Prussia. Wien studied under Helmholtz and Kundt.[1] He invented the… … Wikipedia
Operational amplifier applications — This article illustrates some typical applications of operational amplifiers. A simplified schematic notation is used, and the reader is reminded that many details such as device selection and power supply connections are not shown. Contents 1… … 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
THD analyzer — Total Harmonic Distortion (THD) Analyzers calculate the total distortion introduced by all the harmonics of the fundamental frequency wave. In most cases THD is the amount that is required to calculate, rather than distortion caused by individual … Wikipedia
List of vacuum tubes — This is a list of vacuum tubes or thermionic valves. Before the advent of semiconductor devices, hundreds of tube types were used in consumer and industrial electronics; today only a few types are still used in specialized applications. Contents… … Wikipedia
Positive feedback — Alarm or panic can spread by positive feedback among a herd of animals to cause a stampede. Positive feedback is energy taken from the output of a system and reapplied to the input, which is phase congruent with the input signal. A system… … Wikipedia
Negative resistance — is a property of some electric circuits where an increase in the current entering a port results in a decreased voltage across the same port. This is in contrast to a simple ohmic resistor, which exhibits an increase in voltage under the same… … 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
Electronic oscillator — An electronic oscillator is an electronic circuit that produces a repetitive electronic signal, often a sine wave or a square wave.A low frequency oscillator (LFO) is an electronic oscillator that generates an AC waveform between 0.1 Hz and 10 Hz … Wikipedia
