![]() dBSPL is used as a measure of acoustical sound pressure levels, and is a 20log function.Ī comparison of two measurements or values. ![]() Its reference, 0 dBSPL equals 0.0002 dynes/cm2. Conferencing systems may include projection, monitor displays, computers, satellite connections video and audio playback devices, and much more.Ī measure of sound pressure level measured in dynes per centimeter squared. ![]() The technology by which people separated by distance come together to share information. Most commonly used component in a loudspeaker system and found in all ranges of drivers. ![]() The electrical signal that represents complete color picture information and all synchronization signals, including blanking and the deflection synchronization signals to which the color synchronization signal is added in the appropriate time relationship.Īlso called a capacitor microphone, it transduces sound into electricity using electrostatic principles. Because these signals are independent, processing such as chroma keying is facilitated. The red, green and blue or, more commonly, the Y, R-Y, B-Y signals are encoded onto three wires. An electronic device that converts analog signals, such as video and audio signals, into digital form and compresses them to conserve bandwidth on a transmission path.Ĭolor video in which the brightness (luminance) and color hue and saturation (chrominance) are handled independently. Abbreviated coax.Īn acronym for coder/decoder. Cat-6 features more stringent specifications for crosstalk and system noise (part of the EIA/TIA 568a standard).Ī system of transmitting video signals from the point of origin to single or multiple points equipped to receive signals.Ī cable consisting of a center conductor surrounded by insulating material, concentric outer conductor and optional protective covering, all of circular cross-section. The designation for 100-ohm unshielded twisted-pair cables and associated connecting hardware whose characteristics are specified for data transmission up to 100 Mb/s (part of the EIA/TIA 568A standard).Įnhanced version of the Cat-5 cable standard that adds specifications for far end crosstalk (part of the EIA/TIA 568A standard).Ĭable standard for gigabit ethernet and other interconnect that is backward compatible with Category 5 cable, Cat-5e and Cat-3. Heart-shaped region where some microphones will be most sensitive to sound predominately from the front of the microphone diaphragm and reject sound coming from the sides and rear. Pieces of wood that have been inserted between structural building elements to provide a secure mounting point for finish materials or products.Īn illustration of the signal path through a given system.Ī professional type of video connector featuring a two-pin lock.Ī microphone that relies on reflected sound from a surrounding surface. The number of bits used to describe data. The smallest unit of digital information. Shortened form of binary digit, symbolized by 1s and 0s. The ratio of image width to image height (typically widescreen or standard).Īn electronic device used to manipulate audio signals in some manner.Ī measure of information carrying capacity without distortion. Sound that is extraneous to the intentional audio background noise.Īn electronic device for increasing the strength of electrical signals.Ī method of transmitting information by a continuous but varying signal.
