The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...

Signals are everywhere, even if you don’t think about them much. They’re what make things like streaming a movie, making a phone call, or listening to music possible. But not all signals are created ...

Analog vs. Digital: What’s the Difference? Air temperature, sound loudness,light intensity—in nature, all of these quantities vary smoothly and continuously over a range. Such quantities is called ...

This is just a general question. I know, obviously, that there are RS-232 "serial ports" and IEEE 1284/Centronix ports "parallel ports," and that these are "digital" connections. Then you have things ...

As an analog-world descendant, I always hear comments in the hallway about how digital designers don’t really understand analog issues. Digital designers will go so far as to unsympathetically say the ...

Sensors that measure real-world variables seldom have output signals that can be directly connected to a data converter in a system. Typically, there are requirements to amplify, filter, shift offset, ...
