A parallel LC filter has impedance that's theoretically infinite at its resonant frequency. You can exploit this characteristic to decouple a voltage generator from its load. Doing so lets the ...

Ideal capacitors only exist in textbooks. Every real-world capacitor has additional complexity arising from its physical structure. Two plates separated by a dielectric layer are in series with wire ...

Harmonic distortion is not a problem unless it becomes a problem. Harmonics are a breakdown of a distorted waveform into its separate frequencies, which are integer multiples of the fundamental ...

Something that probably unites many Hackaday readers is an idle pursuit of browsing AliExpress for new pieces of tech. Perhaps it’s something akin to social media doomscrolling without the induced ...

Generating a high-frequency magnetic field can be quite a challenge due to an assortment of technical issues. At high frequency, magnetic-coil impedance is large. It requires a high-voltage and ...
