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.
Decimation, Decimate, or variants may refer to: Decimation (punishment), punitive discipline; Decimation (signal processing), reduction of digital signal's sampling rate;
Decimation is the process of reducing sample rate. Decimation originally meant "take one sample in every 10", but later this term was generalized to simply mean any reduction in sample rate. This electronics-related article is a stub .
The most common choice is a FIR filter for low amounts of decimation (less than ten) or a CIC filter followed by a FIR filter for larger downsampling ratios. Variations on the DDC [ edit ]
Decimalisation or decimalization (see spelling differences) is the conversion of a system of currency or of weights and measures to units related by powers of 10.. Most countries have decimalised their currencies, converting them from non-decimal sub-units to a decimal system, with one basic currency unit and sub-units that are valued relative to the basic unit by a power of 10, most commonly ...
Upsampling requires a lowpass filter after increasing the data rate, and downsampling requires a lowpass filter before decimation. Therefore, both operations can be accomplished by a single filter with the lower of the two cutoff frequencies.
In signal processing, oversampling is the process of sampling a signal at a sampling frequency significantly higher than the Nyquist rate.Theoretically, a bandwidth-limited signal can be perfectly reconstructed if sampled at the Nyquist rate or above it.
