Sampelimiskiirusi

Sampelimiskiirusi is a term used in Estonian-language technical contexts to describe the rate at which samples are captured or processed in digital systems. The word combines sampel (sample) with kiirusi (genitive form of kiirus, speed), effectively meaning sampling speed or sampling rate. In many English-language sources the closest equivalent is the sampling rate or sampling frequency.

In digital audio, sampelimiskiirusi corresponds to the sampling rate, measured in samples per second (hertz). Common standards include 44100 Hz and 48000 Hz, with higher rates such as 96000 Hz or 192000 Hz used for high-resolution audio. The sampling rate determines the highest representable frequency according to the Nyquist theorem, and it interacts with other factors such as bit depth to shape perceived audio quality.

Beyond audio, the concept applies to data acquisition and digital signal processing, where sampelimiskiirusi indicates how often a signal or sensor is sampled per unit time. Higher rates offer better time resolution but generate more data and require more processing power and storage. In practice, engineers balance sampling rate with bandwidth, noise, and system constraints, employing techniques like oversampling, decimation, or downsampling to fit application needs.

Usage notes: the term is more common in Estonian technical writing and may be less familiar in English-language literature, where “sampling rate” is preferred. Context typically clarifies whether the discussion concerns audio, sensors, or general signal processing.
