Sample vs. sample values Is there any difference between the terms sample and sample value in DSP? In statistics, those are very different concepts: a sample is a subset of a population: it is a set of random variables. A sample value is the realization (aka. observed value) of this set.



In DSP, I feel that sample is often used with the same meaning as sample value:
Yes, the confusion comes from sampling theory. Thus, when you sample a signal, you get ... samples. If you want to be clear you can call the other one a statistical sample.
