A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022.210023 considers sub-femtometer-resolution absolute spectroscopy based on dual electro-optic frequency comb. Optical frequency ...

(Nanowerk News) Optical frequency comb (OFC) provides equidistant comb lines in broad bandwidth, and each comb line corresponds to an absolute optical frequency, which is similar as a comb (or rule) ...

The fast Fourier Transform (FFT), added to an oscilloscope or digitizer, permits measuring the frequency domain spectrum of the acquired signals. This provides a different and usually helpful ...

Microwave frequency generation has posed significant challenges to engineers over the years, requiring in-depth knowledge of analog, digital, and radio frequency (RF) and microwave ...

Motion control systems often require digital-to-analog converters with high resolution but not high accuracy. Because high-accuracy DACs are expensive and consume valuable board space, a good solution ...
