  2. Oscillator sync - Wikipedia

    en.wikipedia.org/wiki/Oscillator_sync

    Oscillator sync is a feature in some synthesizers with two or more VCOs, DCOs, or "virtual" oscillators. As one oscillator finishes a cycle, it resets the period of another oscillator, forcing the latter to have the same base frequency .

  3. MOS Technology 6581 - Wikipedia

    en.wikipedia.org/wiki/MOS_Technology_6581

    Oscillator sync for each audio oscillator; Two 8-bit analog-to-digital converters (typically used for game control paddles, but later also used for a mouse) External audio input (for sound mixing with external signal sources) Random number/modulation generator (via reading the state of the 3rd oscillator or 3rd envelope generator)

  4. Holdover in synchronization applications - Wikipedia

    en.wikipedia.org/wiki/Holdover_in...

    A combination of quartz based reference oscillator (such as an OCXO) and modern correction algorithms can get good results in Holdover applications. [23] The holdover capability then is provided either by a free running local oscillator, or a local oscillator that is steered with software that retains knowledge of its past performance. [23]

  5. Kuramoto model - Wikipedia

    en.wikipedia.org/wiki/Kuramoto_model

    Color scale indicates oscillator phase. There are a number of types of variations that can be applied to the original model presented above. Some models change the topological structure, others allow for heterogeneous weights, and other changes are more related to models that are inspired by the Kuramoto model but do not have the same ...

  6. Sync - Wikipedia

    en.wikipedia.org/wiki/Sync

    Sync, a signal used in composite video systems to coordinate the timings of lines, fields and frames; DIN sync, a standard interface for electronic music instruments; Ford Sync, an in-car communications and entertainment system; Oscillator sync, where a slave oscillator is reset by a master oscillator

  7. Ringing artifacts - Wikipedia

    en.wikipedia.org/wiki/Ringing_artifacts

    The sinc function, the impulse response for an ideal low-pass filter, illustrating ringing for an impulse. The Gibbs phenomenon, illustrating ringing for a step function.. By definition, ringing occurs when a non-oscillating input yields an oscillating output: formally, when an input signal which is monotonic on an interval has output response which is not monotonic.

  8. Frequency modulation synthesis - Wikipedia

    en.wikipedia.org/wiki/Frequency_modulation_synthesis

    The (instantaneous) frequency of an oscillator is altered in accordance with the amplitude of a modulating signal. [1] FM synthesis can create both harmonic and inharmonic sounds. To synthesize harmonic sounds, the modulating signal must have a harmonic relationship to the original carrier signal. As the amount of frequency modulation increases ...

  9. MOS Technology VIC - Wikipedia

    en.wikipedia.org/wiki/MOS_Technology_VIC

    MOS Technology VIC (PAL version 6561–101) Pinout diagram of the 6560 version of the MOS VIC chip. This circuit was packaged in a standard 40-pin DIP casing.. The VIC (Video Interface Chip), specifically known as the MOS Technology 6560 (NTSC version) / 6561 (PAL version), is the integrated circuit chip responsible for generating video graphics and sound in the VIC-20 home computer from ...
