A cable modem is a type of modem used to allow computer systems and networks to communicate over cable television infrastructure networks. These networks use coaxial cable media currently defined by the rg6 cable standard in the United States. RG6 cable is usually triple or quadruple shielded, is generally available in 500 or 1000 foot lengths, and has a sweep test range of 1Ghz (1000Mhz). Belden makes specialized and high end coaxial cable that far surpasses the normal standards, including cables that sweep test to 3Ghz or even 4.5Ghz. Cable Read More

An ultrasonic flow meter emits an ultrasonic signal through a liquid and receives the echoes that are reflected off of air bubbles and other discontinuities within the liquid in order to determine the liquid’s speed through its container. Ultrasonic flow meters are used in waste water and other applications that involve changes in pressure or chemicals. Ultrasonic flow meters are ideal for many applications because they require little maintenance and can be used from a remote location. How Ultrasonic Flow Meters Work An ultrasonic flow meter has two separate piezoelectric Read More

JPEG (Joint Photographic Experts Group) is a lossy compression technique for color pictures. Pronounced "jay-peg", JPEG is an ISO/IEC group of experts that creates and maintains standards for a suite of compression algorithm for computer image files. JPEG standards help image files to be compressed to around five percent of their original size, though some details are lost during compression. The commonly used file extensions for th JPEG format are .jpg, .jpeg, .jfif, .or jpe. The extension JPEG specifies only how an image is transformed into a stream of bytes. Read More

Specific gravity is a special case of relative density. That is, a substance’s density is divided by the density of water at 4 F (0 C). Since water has a density of 1 gram/cm3 and all of the units cancel, specific gravity is the same number as density, but without any units (dimensionless). Relative density is another dimensionless number that measures any substance’s density in relation to another. A relative density greater than 1 (one) means that the substance in the numerator has a bigger density than the one in Read More
