Here is a short tutorial on why DC/DC buck converters need capacitors on the input and how it works in a power design.

Matt Dore and the rest of Cambridge Audio’s engineering team explain that, after the run-in-induced relaxation of the suspension, roll surround and spider “reduces the resonance frequency, giving more ...

Abstract: In this paper, a variable-gain LLC converter with a series-parallel hybrid switch-controlled capacitor ... of resonant current to guarantee soft switching. Besides, a mode switching scheme ...

Abstract: This paper investigates the impact of resonant acoustic waves on the frequency noise spectrum of Distributed Feedback fiber lasers. A phase-shifted Fiber Bragg Grating is used to probe ...

The aluminum rod will produce a loud, clear tone that will last for a long time. You can also find the resonant frequencies of flexible pipe or hose. Listen with one end of the hose to your ear while ...
