Frequency, a term to show how many times the wave of the data repeats in a second, is expressed with the unit of Hz (Hertz). Meanwhile, sampling is a technique that is used to convert the analog data to a digital format. Since all the data are processed by a computer, they must go through the process of sampling. The higher the sampling frequency increases, the larger the amount of the digitized data becomes. The available frequencies are 128, 256, 512 and 1,024 Hz. The frequency can be adjusted by moving the frequency selection button with the mouse as in the picture shown below.
