Decimation. Etching by William Hogarth in Beaver's Roman Military Punishments (1725). In the military of ancient Rome, decimation (from Latin decimatio 'removal of a tenth' [1]) was a form of military discipline in which every tenth man in a group was executed by members of his cohort.
This factor multiplies the sampling interval or, equivalently, divides the sampling rate. For example, if compact disc audio at 44,100 samples/second is decimated by a factor of 5/4, the resulting sample rate is 35,280. A system component that performs decimation is called a decimator. Decimation by an integer factor is also called compression ...
Decimation, Decimate, or variants may refer to: Decimation (punishment), punitive discipline; Decimation (signal processing), reduction of digital signal's sampling rate;
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
The term "decimated" is a horrifying one, and evidently is sufficiently horrifying to satisfy many otherwise well-informed writers, so WP desperately needs to deprecate, and otherwise counter, its vague use:
Recall that decimation of sampled data in one domain (time or frequency) produces overlap (sometimes known as aliasing) in the other, and vice versa. Compared to an L {\displaystyle L} -length DFT, the s N {\displaystyle s_{_{N}}} summation/overlap causes decimation in frequency, [ 1 ] : p.558 leaving only DTFT samples least affected by ...
For example, the information encoded in one "fair" coin flip is log 2 (2/1) = 1 bit, and in two fair coin flips is log 2 (4/1) = 2 bits. A 2011 Science article estimates that 97% of technologically stored information was already in digital bits in 2007 and that the year 2002 was the beginning of the digital age for information storage (with ...
