In this paper, we propose a time-frequency analysis method to obtain instantaneous frequencies and the corresponding decomposition by solving an optimization problem. In this optimization problem, the ...
The use of a snubber circuit to damp the voltage ringing stemming from parasitic oscillation in switching voltage regulators (VRs) is often not an option. The components for this circuitry must be ...
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 ...
Measuring low-frequency electric fields remains difficult when traceability, small size, and vector resolution are all required at the same time. A team at Nanyang Technological University, Singapore, ...
In this article, we will explore AC analysis with the “.AC” directive, one of the main techniques for evaluating the frequency response of circuits. It is one of the most powerful features of SPICE ...
The analysis of RF and microwave signals in the frequency domain used to be the forte of the spectrum analyzer, but now it’s become a choice between signal analyzers and digital oscilloscopes. How did ...
