/ˌəʊvəˈsɑːmpl̩ɪŋ/,

/ˌəʊvəˈsampl̩ɪŋ/, U.S.

/ˌoʊvərˈsæmp(ə)lɪŋ/

Origin: Formed within English, by derivation. Etymons: over- prefix, sampling n.

Etymology: < over- prefix + sampling n. Compare slightly later oversample v. and later oversampled adj.

1. gen. Excessive sampling; the taking or providing of too many samples. rare.

ΚΠ

1940 Q. Jrnl. Econ. 54 300 The reviewer is deterred from going into this intriguing problem more fully..by a reluctance to spoil the treat for the reader by over-sampling.

2. Statistics. The sampling of a class of data at a comparatively high frequency relative to other categories; (a) disproportionately high representation in a sample.

ΚΠ

1943 Jrnl. Amer. Statist. Assoc. 38 80 The use of these serial numbers excluded 22 counties from the sample and resulted in an oversampling of the counties with small numbers of farms.

1960 Ecology 41 251/2 A plan that specifies a fixed sample will often result in over-sampling at low and high population levels and under-sampling at intermediate levels.

1986 Jrnl. Higher Educ. 57 62 Over-sampling of the minority student population was intentional because of our..our intent to analyze differences between ethnic groups.

a. Science and Engineering. The sampling of something at a high frequency relative to the frequency of the data; (Electronics, in analogue-to-digital signal conversion) the sampling of an analogue signal at a frequency that is much greater than the Nyquist frequency.

ΚΠ

1966 Philos. Trans. (Royal Soc.) A. 259 545 The advantage of the response method over the harmonic method is related to the degree of oversampling.

1973 J. B. Hagen & D. T. Farley in Radio Sci. 8 775/2 Most of the advantage to be gained by oversampling is realized when the sampling rate is twice the Nyquist rate appropriate to the original signal.

1990 IEEE Internat. Symposium Circuits & Syst. 4 3275/1 Efficient high-resolution analog-to-digital conversion is obtained by using oversampled sigma-delta modulation... With slight changes in the adjustable filter part, the overall filter can be used for many oversampling ratios.

b. Electronics. In the processing of digital signals: the technique or facility of increasing the apparent sampling frequency of a digital signal (usually by a factor of 2, 4, 8, or 16) by repeating each digit a number of times, in order to facilitate the subsequent filtering of unwanted noise.

ΚΠ

1982 Electronics 7 Apr. 74/1 A digital oversampling filter that extracts a 16-bit system's signal-to-noise ratio.

1986 IEEE Jrnl. Solid-state Circuits 21 956/1 The described circuit performs the oversampling of the luminance and two chrominance signals. It doubles the input luminance sampling rate and quadruples the two chrominance ones.

1994 Coloradoan (Fort Collins) 1 Jan. a5 (advt.) This may be a once in a lifetime opportunity to get a full featured CD changer with remote control..and 8 times oversampling.
