Sometimes a simulation might reveal a mystery peak in a waveform, but don’t necessarily let that dissuade you if the circuit is working and EMI or any other potential dangers aren’t lurking. My ...

The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.

Poor power supply quality—in the form of dips, dropouts, and other voltage variations—can result in electrical malfunctions that can have serious consequences. To verify that automotive systems will ...

Electronic products must pass somelevel of immunity tests when subjected to conducted or radiatedenergy. Some of those tests include subjecting the equipment undertest to electrical impulses–short ...

The first major performance item to review is large-signal load-transient response performance. Here, a large-signal phrase is used in contrast to a small-signal. A small-signal transient literally ...

A PQ expert can link an abnormal current or voltage waveform to an abnormal condition on a power system just as a handwriting expert matches a signature to a person. Many facilities now have online ...
