Lithium-ion battery expert Prof. Paul Christensen queries claims made by LG Chem about finding the key to suppressing thermal ...

Learn how microphones and amplifiers work together to convert sound to electrical signals for clear audio output.

A reconfigurable impedance tuner for a high-power transmitter should possess minimal loss, broad Smith Chart coverage, fast reconfigurability, and high-power handling. A periodic capacitor-loaded, ...

However, the grid-supporting capability is commonly overlooked while designing the current limiting method. Therefore, a two-stage adaptive virtual impedance-based current limitation for improved grid ...

The result is a very neat unit far better able do drive high-impedance headphones than the output from an unmodified DAC, but still looking as svelte as any commercial product. We like it.

In my evaluations I use angle capacitors for controlling the resonant length of parasites ... I tried other heights of center element and 25 meters is about the best compromise between pattern and ...

The two capacitors do want to be in roughly the ... and it’s a passive filter which increases the output impedance across the board, making it quieter even for the low-frequency components ...
