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 ...

In the first installment of this course, we learned that a digital value is a quantity that varies “in steps” and can take on only a finite number of values. In today’s logic systems, only two ...

Galvanic isolation is common in industrial and automotive systems as a means of protecting against high voltages or to counteract ground potential differences. Designers traditionally used ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...
