A small team of researchers with the University of California has found a way to pick out a single short radio signal burst among a barrage of background noise. Currently it is impossible to separate out a unique signal if there is just one burst present—there needs to be multiple examples. That could change in the near future as the researchers on this new effort have developed a way to convert radio signals to optical signals that can be processed to filter, separate and identify individual components.
The team started with converting the radio signals to optica...
