sample rate

<digital signal processing> The number of times an analog signal is measured (sampled) per second. The unit of sample rate is "samples per second". This is often expressed in kiloHertz (kHz). For example, "CD quality" sound has a sample rate of 44 kHz. Compare data rate. See Nyquist frequency. [Is it correct to use Hertz for things other than the frequency of a sine wave?] (2001-06-06)

Sample-rate conversion

CHANGING THE SAMPLING RATE OF A DISCRETE SIGNAL TO OBTAIN A NEW DISCRETE REPRESENTATION OF THE UNDERLYING CONTINUOUS SIGNAL

Resampling (audio); Wave Resample; Audio resampling; Multi-rate digital signal processing; Sample rate conversion; Sample rate converter; Sample-rate converter

Sample-rate conversion, sampling-frequency conversion or resampling is the process of changing the sampling rate or sampling frequency of a discrete signal to obtain a new discrete representation of the underlying continuous signal. Application areas include image scaling and audio/visual systems, where different sampling rates may be used for engineering, economic, or historical reasons.

Paul Sample (artist)

AMERICAN ARTIST (1896-1974)

Paul Starrett Sample

Paul Starrett Sample (September 14, 1896 in Louisville, Kentucky – February 26, 1974 in Norwich, Vermont) was an American artist who portrayed life in New England in the middle of the 20th Century with a style that showed elements of "Social Realism and Regionalism."

Sampling (signal processing)

In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave to a sequence of "samples". A sample is a value of the signal at a point in time and/or space; this definition differs from the term's usage in statistics, which refers to a set of such values.

A sampler is a subsystem or operation that extracts samples from a continuous signal. A theoretical ideal sampler produces samples equivalent to the instantaneous value of the continuous signal at the desired points.

The original signal can be reconstructed from a sequence of samples, up to the Nyquist limit, by passing the sequence of samples through a type of low-pass filter called a reconstruction filter.
