WebApr 3, 2024 · Sampling rate. The sampling rate describes the number of times that the signal is measured per unit of time, usually given in Hertz (Hz) = 1/second (Figure 1). Notice that although the EEG is an analog signal (continuous in time), it has to be converted into a digital signal (discrete in time) in order to be processed by the computer.
