the smaller the voltage steps in which the input range of the instrument is divided.
The acquired numbers can be used for various purposes, e.g. to create a graph.

The sine wave in figure

is sampled at the dot positions. By connecting the

adjacent samples, the original signal can be reconstructed from the samples. You
can see the result in figure

Sampling rate

The rate at which the samples are taken is called the

sampling rate

, the number

of samples per second. A higher sampling rate corresponds to a shorter interval
between the samples. As is visible in figure

3.3

with a higher sampling rate, the

original signal can be reconstructed much better from the measured samples.
