  2. Electronic oscillator - Wikipedia

    en.wikipedia.org/wiki/Electronic_oscillator

    Simple relaxation oscillator made by feeding back an inverting Schmitt trigger's output voltage through a RC network to its input.. An electronic oscillator is an electronic circuit that produces a periodic, oscillating or alternating current (AC) signal, usually a sine wave, square wave or a triangle wave, [1] [2] [3] powered by a direct current (DC) source.

  3. Delta-sigma modulation - Wikipedia

    en.wikipedia.org/wiki/Delta-sigma_modulation

    Each "F" stands for flip-flop and each "G" is a gate, controlled by the 110 kHz oscillator. The principle of improving the resolution of a coarse quantizer by use of feedback, which is the basic principle of delta-sigma conversion, was first described in a 1954-filed patent by C. Chapin Cutler of Bell Labs. [6]

  4. Oscillator (technical analysis) - Wikipedia

    en.wikipedia.org/.../Oscillator_(technical_analysis)

    An oscillator in technical analysis of financial markets is an indicator that informs if the price of a financial instrument is very high or very low, indicating whether it is overbought or oversold. This helps traders make decisions about when to trade (buy or sell) that instrument.

  5. Colpitts oscillator - Wikipedia

    en.wikipedia.org/wiki/Colpitts_oscillator

    The Pierce oscillator, with two capacitors and one inductor, is equivalent to the Colpitts oscillator. [8] Equivalence can be shown by choosing the junction of the two capacitors as the ground point. An electrical dual of the standard Pierce oscillator using two inductors and one capacitor is equivalent to the Hartley oscillator.

  6. Oscillation - Wikipedia

    en.wikipedia.org/wiki/Oscillation

    An undamped spring–mass system is an oscillatory system. Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states.

  7. Crystal oscillator - Wikipedia

    en.wikipedia.org/wiki/Crystal_oscillator

    A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric crystal as a frequency-selective element. [1] [2] [3] The oscillator frequency is often used to keep track of time, as in quartz wristwatches, to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers.

  8. Klystron - Wikipedia

    en.wikipedia.org/wiki/Klystron

    Electrically, this is similar to the two cavity oscillator klystron with considerable feedback between the two cavities. Electrons exiting the source cavity are velocity modulated by the electric field as they travel through the drift tube and emerge at the destination chamber in bunches, delivering power to the oscillation in the cavity.

  9. Wien bridge oscillator - Wikipedia

    en.wikipedia.org/wiki/Wien_bridge_oscillator

    The oscillator is based on a bridge circuit originally developed by Max Wien in 1891 for the measurement of impedances. [1] The bridge comprises four resistors and two capacitors. The oscillator can also be viewed as a positive gain amplifier combined with a bandpass filter that provides positive feedback. Automatic gain control, intentional ...
