Analog Signal Signals Text book Textbook Variables

Click For Summary

The discussion revolves around the definition and examples of analog signals, particularly those dependent on noncontinuous variables. Participants debate whether the textbook's claim that analog signals can be noncontinuous is accurate, with some suggesting it may refer to concepts like pulse-width modulation or discrete-time analog signals. The distinction between analog and digital signals is clarified, emphasizing that all physical voltages are analog, even when representing digital information. There is consensus that terminology can be imprecise, and a clearer understanding of these concepts is necessary for effective communication in electrical engineering. The conversation highlights the complexities of signal classification and the importance of precise language in technical discussions.

Well, that's a relief.
I guess I would refer to what you're talking about would be something like 'Time- windowed sampling'. But at least we basically agree and we aren't getting into a fight about it.

I did get the sense we agreed, even if we didn't know it yet. ;)

I think "time-windowed sampling" would be a fine way to describe this kind of signal. I use the term "discrete-time analog" primarily because that is the term used in the analog IC business (these kinds are systems are almost always integrated). Since the OP is a student it is good to at least start by using generally accepted terms whenever possible.
