  2. Coordinated Video Timings - Wikipedia

    en.wikipedia.org/wiki/Coordinated_Video_Timings

    The parameters defined by standard include horizontal blanking and vertical blanking intervals, horizontal frequency and vertical frequency (collectively, pixel clock rate or video signal bandwidth), and horizontal/vertical sync polarity. The standard was adopted in 2002 and superseded the Generalized Timing Formula.

  3. Generalized Timing Formula - Wikipedia

    en.wikipedia.org/wiki/Generalized_Timing_Formula

    Generalized Timing Formula is a standard by VESA which defines exact parameters of the component video signal for analogue VGA display interface.. The video parameters defined by the standard include horizontal blanking (retrace) and vertical blanking intervals, horizontal frequency and vertical frequency (collectively, pixel clock rate or video signal bandwidth), and horizontal/vertical sync ...

    1 = with serrations (H-sync during V-sync). Bit 1: Sync on red and blue lines additionally to green 0 = sync on green signal only; 1 = sync on all three (RGB) video signals. Bits 4–3 = 10 Digital sync., composite (on HSync). If set, the following bit definitions apply: Bit 2: Serration. 0 = without serration; 1 = with serration (H-sync during ...

    en.wikipedia.org/wiki/Video-signal_generator

    In standard-definition applications, a bi-level sync signal, often with a colorburst signal in facilities that have analog equipment. Typically, this is either in NTSC or PAL format. As the resulting signal is usually indistinguishable from an all-black television signal of the same format, this sort of reference is commonly known as black or ...

  6. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms.

  7. Photon polarization - Wikipedia

    en.wikipedia.org/wiki/Photon_polarization

    Photon polarization is the quantum mechanical description of the classical polarized sinusoidal plane electromagnetic wave.An individual photon can be described as having right or left circular polarization, or a superposition of the two.

  8. Optical rotation - Wikipedia

    en.wikipedia.org/wiki/Optical_rotation

    Optical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials.

  9. Polarizability - Wikipedia

    en.wikipedia.org/wiki/Polarizability

    The polarizability of an atom or molecule is defined as the ratio of its induced dipole moment to the local electric field; in a crystalline solid, one considers the dipole moment per unit cell. [1] Note that the local electric field seen by a molecule is generally different from the macroscopic electric field that would be measured externally.
