  2. Downsampling (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Downsampling_(signal...

    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 ...

  3. Decimation - Wikipedia

    en.wikipedia.org/wiki/Decimation

    Decimation, Decimate, or variants may refer to: Decimation (punishment), punitive discipline; Decimation (signal processing), reduction of digital signal's sampling rate;

  4. Sentence function - Wikipedia

    en.wikipedia.org/wiki/Sentence_function

    The declarative sentence is the most common kind of sentence in language, in most situations, and in a way can be considered the default function of a sentence. What this means essentially is that when a language modifies a sentence in order to form a question or give a command, the base form will always be the declarative.

  5. Discrete-time Fourier transform - Wikipedia

    en.wikipedia.org/wiki/Discrete-time_Fourier...

    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 ...

  6. Decimation (punishment) - Wikipedia

    en.wikipedia.org/wiki/Decimation_(punishment)

    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 ...

  7. Sentence (mathematical logic) - Wikipedia

    en.wikipedia.org/wiki/Sentence_(mathematical_logic)

    Sentences are then built up out of atomic sentences by applying connectives and quantifiers. A set of sentences is called a theory; thus, individual sentences may be called theorems. To properly evaluate the truth (or falsehood) of a sentence, one must make reference to an interpretation of the theory.

  8. List of mathematical functions - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_functions

    Transcendental functions are functions that are not algebraic. Exponential function: raises a fixed number to a variable power. Hyperbolic functions: formally similar to the trigonometric functions. Inverse hyperbolic functions: inverses of the hyperbolic functions, analogous to the inverse circular functions.

  9. Sentence (linguistics) - Wikipedia

    en.wikipedia.org/wiki/Sentence_(linguistics)

    In linguistics and grammar, a sentence is a linguistic expression, such as the English example "The quick brown fox jumps over the lazy dog." In traditional grammar , it is typically defined as a string of words that expresses a complete thought, or as a unit consisting of a subject and predicate .
