A tuned circuit formed by a capacitor and an inductor is a familiar enough circuit, and it’s understood that it will resonate at a particular frequency. As that frequency increases, so the size of the ...

Modern radios are often digital affairs, in which the frequency is derived from a stable crystal oscillator and varied through a microprocessor controlled frequency synthesiser. It won’t drift, and it ...

Quantum hardware is starting to hit a wall that has little to do with flashy new qubit designs and everything to do with how ...

Scientists have created a toolkit for synthetic biologists who need to precisely tune the input and output levels of genetic circuits. Rice University scientists have created a toolkit for synthetic ...

VARIABLE condensers are now so commonly employed in radio receivers to tune circuits including a constant inductance that the use, some years ago, of variable inductances or variometers with fixed ...

While LCR meters are readily available at reasonable cost, they do not measure the Q of an inductor. This circuit enables you to measure the Q of inductors with the aid of an RF signal generator. A ...

Osaka, Japan – Researchers from SANKEN (The Institute of Scientific and Industrial Research) at Osaka University and JOANNEUM RESEARCH (Weiz, Austria), have shown how exposing an organic polymer to ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

Japanese scientist have treated the brain like a tuned circuit to get accurate intracranial pressure (ICP) measurements without invasive surgery. ICP is a valuable parameter, for example in ...

Researchers created flexible integrated circuits precisely tuned by illuminating an organic polymer with ultraviolet light. This work may allow for inexpensive electronics to be incorporated into ...
