sample rate
     
         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?]
