  2. Clock signal - Wikipedia

    en.wikipedia.org/wiki/Clock_signal

    Clock signal and legend. In electronics and especially synchronous digital circuits, a clock signal (historically also known as logic beat) [1] is an electronic logic signal (voltage or current) which oscillates between a high and a low state at a constant frequency and is used like a metronome to synchronize actions of digital circuits.

  3. 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.

  4. Digital pattern generator - Wikipedia

    en.wikipedia.org/wiki/Digital_pattern_generator

    Digital pattern generators are today available as stand-alone units, add-on hardware modules for other equipment such as a [logic analyzer] or as PC-based equipment.. Stand-alone units are self-contained devices that include everything from the user interface to define the patterns that should be generated to the electronic equipment that actually generates the output signal.

  5. Flip-flop (electronics) - Wikipedia

    en.wikipedia.org/wiki/Flip-flop_(electronics)

    As the clock signal goes high (0 to 1) the inverted "enable" of the first latch goes low (1 to 0) and the value seen at the input to the master latch is "locked". Nearly simultaneously, the twice inverted "enable" of the second or "slave" D latch transitions from low to high (0 to 1) with the clock signal.

  6. Synchronous circuit - Wikipedia

    en.wikipedia.org/wiki/Synchronous_circuit

    In digital electronics, a synchronous circuit is a digital circuit in which the changes in the state of memory elements are synchronized by a clock signal. In a sequential digital logic circuit, data is stored in memory devices called flip-flops or latches. The output of a flip-flop is constant until a pulse is applied to its "clock" input ...

  7. Digital delay generator - Wikipedia

    en.wikipedia.org/wiki/Digital_delay_generator

    A flipflop-based dual-rank synchronizer can be used to synchronize an external trigger to a counter-based delay generator, as in case (1) above. It is then possible to measure the skew between the input trigger and the local clock and adjust the vernier delay on a shot-by-shot basis, to compensate for most of the trigger-to-clock jitter.

  9. Image trigger - Wikipedia

    en.wikipedia.org/wiki/Image_trigger

    An image trigger initiates the capture of single or multiple frames of a digital camera by analysing the signals of its sensor. For capturing and analysing of fast moving objects (e.g. as in quality control of production lines) modern high speed cameras are frequently used. Typically the initiation of an image-series starts as soon as the ...
