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 ...

Researchers have invented new tools for decoding and controlling signalling circuits in living cells with flashes of light. In principle, any cellular circuit can now be targeted with the new method.

Last month in Part 1 we looked at one issue of using conductive shields in our high-frequency circuits. We showed that they can and do resonate at frequencies and we can easily calculate the lowest ...

For quantum computers to change the game of computation, scientists need to show that the machines’ calculations are correct. Now, there’s hope. Google’s Willow quantum chip has achieved verifiable ...

For an undamped LC circuit excited by an AC voltage source through simple phaser equations, we come to see that the circuit becomes short circuited at the resonant frequency. However if we analyze the ...
