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 ...
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 The standard was adopted in 2002 and superseded the Generalized Timing Formula.
1 = with serration (H-sync during V-sync). Bit 1: Horizontal sync polarity: 0 = negative; 1 = positive. Bits 4–3 = 11 Digital sync., separate If set, the following bit definitions apply: Bit 2: Vertical sync polarity: 0 = negative; 1 = positive. Bit 1: Horizontal sync polarity: 0 = negative; 1 = positive. Bit 0 Stereo mode (combines with bits ...
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.
A symmetry plane parallel with the principal axis is dubbed vertical (σ v) and one perpendicular to it horizontal (σ h). A third type of symmetry plane exists: If a vertical symmetry plane additionally bisects the angle between two 2-fold rotation axes perpendicular to the principal axis, the plane is dubbed dihedral (σ d). A symmetry plane ...
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 ...
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.
In geology, the terms sinistral and dextral refer to the horizontal component of the movement of blocks on either side of a fault or the sense of movement within a shear zone. These are terms of relative direction, as the movement of the blocks is described relative to each other when viewed from above.
