All periodic signals can be described in terms of amplitude and phase. We all learned that in basic circuit theory. You surely recall having to calculate signal’s phase change when it passed through a ...

Measuring the phase difference between two periodical signals is often required for a science such as meteorology, computing, and communications. An oscilloscope offers a quick and simple way to make ...

Autofocus technology is one of the key pillars of mobile photography, ensuring crisp, clean captures of even the fastest-moving subjects. But did you know that autofocus comes in a variety of types?
