  2. Betamax - Wikipedia

    en.wikipedia.org/wiki/Betamax

    In June 1983, Sony introduced high fidelity audio to videotape as Beta Hi-Fi. For NTSC , Beta HiFi worked by placing a pair of FM carriers between the chroma (C) and luminance (Y) carriers, a process known as frequency multiplexing.

  3. Beta3-adrenergic agonist - Wikipedia

    en.wikipedia.org/wiki/Beta3-adrenergic_agonist

    The β 3 (beta 3) adrenergic receptor agonist or β 3-adrenoceptor agonist, also known as β 3-AR agonist, are a class of medicine that bind selectively to β 3-adrenergic receptors. β 3 -AR agonists for the treatment of obesity and type 2 diabetes have been in developmental stages within many large pharmaceutical companies since the early ...

  4. Beta-3 adrenergic receptor - Wikipedia

    en.wikipedia.org/wiki/Beta-3_adrenergic_receptor

    The beta-3 adrenergic receptor (β 3-adrenoceptor), also known as ADRB3, is a beta-adrenergic receptor, and also denotes the human gene encoding it.

  5. Environmental Audio Extensions - Wikipedia

    en.wikipedia.org/wiki/Environmental_Audio_Extensions

    The Environmental Audio Extensions (or EAX) are a number of digital signal processing presets for audio, present in Creative Technology Sound Blaster sound cards starting with the Sound Blaster Live and the Creative NOMAD/Creative ZEN product lines.

  6. Neural oscillation - Wikipedia

    en.wikipedia.org/wiki/Neural_oscillation

    Oscillations have been commonly reported in the motor system. Pfurtscheller and colleagues found a reduction in alpha (8–12 Hz) and beta (13–30 Hz) oscillations in EEG activity when subjects made a movement.

  7. Beta wave - Wikipedia

    en.wikipedia.org/wiki/Beta_wave

    Beta waves can be split into three sections: Low Beta Waves (12.5–16 Hz, "Beta 1"); Beta Waves (16.5–20 Hz, "Beta 2"); and High Beta Waves (20.5–28 Hz, "Beta 3"). Beta states are the states associated with normal waking consciousness.

  8. Shure Beta 58A - Wikipedia

    en.wikipedia.org/wiki/Shure_Beta_58A

    The Shure Beta 58A is a rugged [when defined as?] dynamic supercardioid microphone developed by Shure Incorporated specifically for live vocal performances. The microphone won a TEC Award in 1996 for outstanding microphone technology.

  9. Theta wave - Wikipedia

    en.wikipedia.org/wiki/Theta_wave

    In the oldest EEG literature dating back to the 1920s, Greek letters such as alpha, beta, theta, and gamma were used to classify EEG waves falling into specific frequency ranges, with "theta" generally meaning a range of about 4–7 cycles per second (Hz).

  10. Nonlinear acoustics - Wikipedia

    en.wikipedia.org/wiki/Nonlinear_acoustics

    Nonlinear acoustics (NLA) is a branch of physics and acoustics dealing with sound waves of sufficiently large amplitudes. Large amplitudes require using full systems of governing equations of fluid dynamics (for sound waves in liquids and gases) and elasticity (for sound waves in solids).

  11. Betacam - Wikipedia

    en.wikipedia.org/wiki/Betacam

    Betacam was initially introduced as a camera line along with a video cassette player. The first cameras were the BVP-3, which utilized three Saticon tubes, the BVP-30, which utilized three Plumbicon tubes, and the BVP-1, which used a single tri-stripe SMF (Saticon Mixed Field) Trinicon tube.
