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?]
Every sample must still be accompanied by a letter, a circumstance which made the application of the sample rate heavy.
In 1875 the sample rate was simplified by the introduction of a single rate of 10 pf.
The sample rate was, moreover, complicated as compared with the letter rate.
