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 ...

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 ...

AT a meeting of the Students Section of the Institution of Electrical Engineers held on November 16, Mr. C. W. Eggleton read a paper on “The Frequency Stability of Tuned Circuits”. The author dealt ...
