The Korea Research Institute of Standards and Science (KRISS) on Sept. 10 said its nano proton research team has succeeded in developing a standard signal generating device. According to the KRISS, the new device can generate over 100 times more accurate signals than the existing generators at low voltage of 100 mV.
For the new signal generator, digital signals are converted into analog ones to generate static-free signals and make no errors in them, with the help of the superconductor Josephson device.
The KRISS will make the most of the new technology for research on signal processing, verification of amplifier performance, development of technologies of the defense industry and space and aviation, and the phenomenon of noise temperature.
A senior researcher at the KRISS said, "Accuracy of the signal generator is the most important in accurately evaluating the reception capacity of vehicle navigation systems or mobile phones. Only a few nations, such as the United States, Germany and the Netherlands, possess such a technology."
