42sedimentary rock — Rock formed at or near the Earth s surface by the accumulation and lithification of fragments of preexisting rocks or by precipitation from solution at normal surface temperatures. Sedimentary rocks can be formed only where sediments are… …
43Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… …
44Illustration of the central limit theorem — This article gives two concrete illustrations of the central limit theorem. Both involve the sum of independent and identically distributed random variables and show how the probability distribution of the sum approaches the normal distribution… …
45Gaussian filter — In electronics and signal processing, a Gaussian filter is a filter whose filter window is the Gaussian function:x mapsto sqrt{frac{a}{picdot e^{ a cdot x^2}or with the standard deviation as parameter:x mapsto frac{1}{sqrt{2cdotpi}cdotsigma}cdot… …
46Linear regression — Example of simple linear regression, which has one independent variable In statistics, linear regression is an approach to modeling the relationship between a scalar variable y and one or more explanatory variables denoted X. The case of one… …
47Normal probability plot — The normal probability plot is a graphical technique for normality testing: assessing whether or not a data set is approximately normally distributed. Example of a normal probability plot. The data are plotted against a theoretical normal… …
48Vectorscope — A vectorscope is a special type of oscilloscope used in both audio and video applications. Whereas an oscilloscope or waveform monitor normally displays a plot of signal vs. time, a vectorscope displays an X Y plot of two signals, revealing… …
49Instrument approach — Terminal procedures for an ILS approach in the United States. (The disclaimers shown in red in the illustration do not appear on the original approach plate.) For aircraft operating under instrument flight rules (IFR), an instrument approach or… …
