The term decimation was first used in English to mean a tax of one-tenth (or tithe). Through a process of semantic change starting in the 17th century, the word evolved to refer to any extreme reduction in the number of a population or force, or an overall sense of destruction and ruin, not strictly in the punitive sense or to a reduction by ...
Decimation is a term that historically means the removal of every tenth one. [ a ] But in signal processing, decimation by a factor of 10 actually means keeping only every tenth sample. This factor multiplies the sampling interval or, equivalently, divides the sampling rate.
A cohort selected for punishment by decimation was divided into groups of ten; each group cast lots, and the soldier on whom the lot fell was executed by his nine comrades, often by stoning or clubbing. The remaining soldiers were given rations of barley instead of wheat and forced to sleep outside of the Roman encampment.
Decimation, Decimate, or variants may refer to: Decimation (punishment), punitive discipline; Decimation (signal processing), reduction of digital signal's sampling rate;
The accounts also spell out the punishment that thieves received. The sentence varied from the removal of the thief's ears or nose. One punishment was execution. [2] The 3rd century Chinese text Lüshi Chunqiu advised mourners to plan simple burials to discourage looting. [3] Many Chinese were buried with valuables, including jade burial suits. [4]

Generally speaking, using decimation is very common in multirate filter designs. In the second step, after using decimation, interpolation will be used to restore the sampling rate. The advantage of using decimators and interpolator is that they can reduce the computations when resulting in a lower sampling rate.
