    Sony WH-CH720N features and performance The 720N supports multipoint connectivity, meaning it can pair with two devices instead of just one. That's great if you want to alternate using it with ...

  3. Headphones - Wikipedia

    en.wikipedia.org/wiki/Headphones

    Headphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers , which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker , which emits sound into the open air for anyone ...

    en.wikipedia.org/wiki/PlayStation_Analog_Joystick

    The PlayStation Analog Joystick (SCPH-1110) is Sony's first analog controller for the PlayStation, and is the precursor to the PlayStation Dual Analog Controller.It is often incorrectly [1] referred to as the "Sony Flightstick" (not to be confused with the Flightstick line of joysticks for PlayStation consoles by third-party peripheral manufacturer Hori).

    en.wikipedia.org/wiki/25-pair_color_code

    The wire pairs are referenced directly by their color combination, or by the pair number. For example, pair 9 is also called the red-brown pair. In technical tabulations, the colors are often suitably abbreviated. Violet is the standard name in the telecommunications and electronics industry, but it is sometimes referred to as purple.

    en.wikipedia.org/wiki/Differential_signalling

    The technique sends the same electrical signal as a differential pair of signals, each in its own conductor. The pair of conductors can be wires in a twisted-pair or ribbon cable or traces on a printed circuit board. Electrically, the two conductors carry voltage signals which are equal in magnitude, but of opposite polarity. The receiving ...

    Euler's Tonnetz. The Tonnetz originally appeared in Leonhard Euler's 1739 Tentamen novae theoriae musicae ex certissismis harmoniae principiis dilucide expositae.Euler's Tonnetz, pictured at left, shows the triadic relationships of the perfect fifth and the major third: at the top of the image is the note F, and to the left underneath is C (a perfect fifth above F), and to the right is A (a ...

  8. Coplanar waveguide - Wikipedia

    en.wikipedia.org/wiki/Coplanar_waveguide

    Coplanar waveguides play an important role in the field of solid state quantum computing, e.g. for the coupling of microwave photons to a superconducting qubit.In particular the research field of circuit quantum electrodynamics was initiated with coplanar waveguide resonators as crucial elements that allow for high field strength and thus strong coupling to a superconducting qubit by confining ...

  9. Base pair - Wikipedia

    en.wikipedia.org/wiki/Base_pair

    An unnatural base pair (UBP) is a designed subunit (or nucleobase) of DNA which is created in a laboratory and does not occur in nature. DNA sequences have been described which use newly created nucleobases to form a third base pair, in addition to the two base pairs found in nature, A-T (adenine – thymine) and G-C (guanine – cytosine).
