Many power ICs use frequency jitter, which spreads a control signal's spectrum, to control EMI (electromagnetic interference). If you need to add frequency jitter to power ICs that control three-phase ...

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 ...

Here’s a quick way to determine the bandwidth of a signal when all you know is the clock frequency. Remember: before you start using rules of thumb, be sure to read the Rule of Thumb #0: Use rules of ...

Frequency estimation is a critical aspect of modern signal processing, underpinning advances in communications, radar, biomedical imaging and many other fields. At its core, this discipline seeks to ...

If you want to extract a signal from a huge amount of noise, a lock-in amplifier is the ideal tool. But when it comes to buying one, doing your homework first can avoid a costly mistake, advises ...
