  2. Noise gate - Wikipedia

    en.wikipedia.org/wiki/Noise_gate

    A noise gate or simply gate is an electronic device or software that is used to control the volume of an audio signal. Comparable to a limiter, which attenuates signals above a threshold, such as loud attacks from the start of musical notes, noise gates attenuate signals that register below the threshold. [1] However, noise gates attenuate ...

  3. Dynamic range compression - Wikipedia

    en.wikipedia.org/wiki/Dynamic_range_compression

    A noise gate can be thought of as an extreme form of downward expansion as the noise gate make the quiet sounds (for instance: noise) quieter or even silent, depending on the floor setting. [2] Upward expansion makes the louder sounds above the threshold even louder.

  4. Noise reduction - Wikipedia

    en.wikipedia.org/wiki/Noise_reduction

    Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio.

  5. Noise (electronics) - Wikipedia

    en.wikipedia.org/wiki/Noise_(electronics)

    Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.

  6. Noise (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Noise_(signal_processing)

    Noise reduction, the recovery of the original signal from the noise-corrupted one, is a very common goal in the design of signal processing systems, especially filters. The mathematical limits for noise removal are set by information theory .

  7. Active noise control - Wikipedia

    en.wikipedia.org/wiki/Active_noise_control

    The signals are processed to cancel the noise from the desired signal, producing improved voice sound quality. In some cases, noise can be controlled by employing active vibration control. This approach is appropriate when the vibration of a structure produces unwanted noise by coupling the vibration into the surrounding air or water.

    It’s a lot of talk, a lot of noise, which I’m cool with. It doesn’t bother me at all. I love that. I thrive at it. It keeps you all wondering, the world wondering. It’s good to be talked ...

  9. Ferrite bead - Wikipedia

    en.wikipedia.org/wiki/Ferrite_bead

    A ferrite bead – also called a ferrite block, ferrite core, ferrite ring, EMI filter, or ferrite choke [1] [2] – is a type of choke that suppresses high-frequency electronic noise in electronic circuits. Ferrite beads employ high-frequency current dissipation in a ferrite ceramic to build high-frequency noise suppression devices.
