  2. Quartz clock - Wikipedia

    en.wikipedia.org/wiki/Quartz_clock

    Quartz clock. Circuit board of an e block from a chronograph -wristwatch. Quartz oscillator crystal on right. Quartz clocks and quartz watches are timepieces that use an electronic oscillator regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks and watches are at ...

  3. 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.

  5. Electronic oscillator - Wikipedia

    en.wikipedia.org/wiki/Electronic_oscillator

    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. Oscillators are found in many electronic devices, such as radio receivers, television sets, radio and television ...

  6. Pierce oscillator - Wikipedia

    en.wikipedia.org/wiki/Pierce_oscillator

    The Pierce oscillator is a type of electronic oscillator particularly well-suited for use in piezoelectric crystal oscillator circuits. Named for its inventor, George W. Pierce (1872–1956), [1][2] the Pierce oscillator is a derivative of the Colpitts oscillator. Virtually all digital IC clock oscillators are of Pierce type, as the circuit can ...

  7. Clock generator - Wikipedia

    en.wikipedia.org/wiki/Clock_generator

    A clock generator is an electronic oscillator that produces a clock signal for use in synchronizing a circuit's operation. The signal can range from a simple symmetrical square wave to more complex arrangements. The basic parts that all clock generators share are a resonant circuit and an amplifier. The resonant circuit is usually a quartz ...
