Detailed explanation-1: -The units for sample rate are samples per second (sps) or Hertz (Hz). The two are equivalent since the Hertz is equal to the reciprocal second, [Hz]=[s-1]. Hertz is the unit for frequency, and the sample rate is sometimes referred to as the sampling frequency.
Detailed explanation-2: -Expressed in Hertz, the sample rate of GPS technology is the number of times per second that the chipset and satellites communicate to establish the device location. For example, a device with a 1Hz sample rate receives location once per second, while a 10Hz device receives it 10 times per second.
Detailed explanation-3: -Definition: Sampling rate or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete or digital signal.
Detailed explanation-4: -For a 100 Hertz sine wave, the minimum sampling rate would be 1000 samples per second.
