A new method devised by researchers at the U.K.'s Imperial College London (ICL) and Germany's Technical University of Munich could support unlimited digital sensing.
The team used modulo-sampling analog-to-digital converters (ADCs) to determine whether sensors could process more information via a different type of voltage; the researchers built a prototype with an algorithm that causes the ADC to switch to modulo voltage once a stimulus limit is reached, and folds these signals into smaller ones.
Potential applications include enhanced imaging, audio perception, and improved driverless-car cameras.
Said ICL's Ayush Bhandari, "By combing new algorithms and new hardware, we have fixed a common problem—one that could mean our digital sensors perceive what humans can, and beyond."
