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 ...

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 ...

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 ...

As discussed in Part 1 of this series, as the frequency of a single or coupled tuned circuits is increased, the selectivity decreases to the point that there may be insufficient selectivity at 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 ...

The hormone oxytocin helps mammals, including people, form strong social bonds. A new study in mice reports that the peptide may forge these relationships by tuning neural circuits to respond to ...
