Data Acquisition

dedicated electronic circuitry. In spite of this,DRAM chips are cheaper and consume less powerthan their static counterparts, and they aretherefore used more extensively in modern PCs.RAMDACRangeRange selectRange selectRasterReal-timeReflectance componentRefresh rateResolutionResolutionResponse timeRGBRandom access memory digital-to-analogconverter.The difference between the upper and lower limitsof the measured value.The full-scale range a board uses is selected by oneof three methods: through the DAS software, by ahardware jumper on the board, or through theuse of an external reference voltage.The feature on a board (either via software, or byhardware DIP switch or jumper) to change theincoming analog or output analog range voltagerange.The pattern of lines traced by rectilinear scanningin display systems.A system is capable of operating in real-time whenit is fast enough to react to the real-world events.The amount of light reflected by an object in thescene being viewed.The speed at which information is updated on acomputer display (CRT).The number of bits in which a digitized value willbe stored. This represents the number of divisionsinto which the full-scale range will be divided; forexample, a 0–10 V range with a 12–bit resolutionwill have 4096 (2 12 ) divisions of 2.44 mV each(10 V/2 12 or 10 V/4096).The number of pixels that may be displayed on amonitor screen.The elapsed time between the generation of thelast character of a message at a terminal and thereceipt of the first character of the reply. Itincludes terminal delay and network delay.Red/green/blue. An RGB signal has four separateelements; red/green/blue and sync. This results ina cleaner image than with composite signals due tothe lower level of distortion and interference.RLERun length encoder. A digital image method
