The analysis of electrical signals, otherwise known as signal analysis, is a fundamental challenge for virtually all electronic design engineers and scientists. While it provides valuable insight into ...

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 ...

The fast Fourier Transform (FFT), added to an oscilloscope or digitizer, permits measuring the frequency domain spectrum of the acquired signals. This provides a different and usually helpful ...

The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...

Lock-in amplifiers were invented in the 1930s [1, 2, 3] and commercialized [4] in the mid 20 th century as electrical instruments that are capable of extracting signal amplitudes and phases in ...

We’re all familiar with the general idea of a filter: it removes something that we don’t want from something we do want. Coffee filters that pass the liquid coffee but retain the grounds or air ...

A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare. Army ...
