Thin-film lithium niobate microresonator Raman lasing suppression methods and octave-spanning frequency combs. a, Thin-film lithium niobate microresonator Raman lasing suppression methods, including ...

Sound-level measurements offer a conventional way to measure sound but do not contain frequency information, making it difficult to compare different sounds or vibration. Octave analysis filters the ...

Editor’s Note: This DI is a two-part series. Part 1 shows how to make an oscillator with a pitch that is proportional to a control voltage. Part 2 shows how to modify the circuit for use with higher ...

The high-speed, 11-bit 349-series of PIN diode attenuators covers the 1.0 to 18 GHz range. Operating over octave frequency bands, the digitally controlled attenuators switch in less than 300 ns. Both ...

Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor ...
