There is no such thing as a “frequency domain” — there is only dv/dt. This artificial notion was born in 1807, when mathematician Joseph Fourier announced to the French Academy a discovery so ...

Finite-Difference Time-Domain (FDTD) methods have long served as a workhorse for simulating electromagnetic wave propagation. In dispersive media, where material responses vary with frequency, the ...

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 ...

Every electronic circuit has some noise and it can affect both analog and digital circuits. Some noise comes from outside interference while some comes from random factors such as thermal effects.

The launch of new products and options during June has boosted engineers’ choices for both time- and frequency-domain analyses. In the latter category, Anritsu added differential noise-figure ...

AI-driven process monitoring enhances the qualification of additively manufactured stainless-steel parts. By analysing high-frequency welding current and voltage signals in both the time and frequency ...
