electronic jamming communications is n’t a new theme , but with battlefield becoming increasingly digital , it ’s an evermore pertain threat . Now , though , DARPA has make a A-one - fast flake that will help create devices able to shrug off wireless - frequency attack .
The Agency ’s build up a new analog - to - digital converter — a twist that takes analogue signals , such as communication theory being send through the atmosphere , and convert them to the digital signals that potentially represent the entropy content held within . But this piece of music of electronics is seriously fast : it ’s able to sample and digitize sign at a rate of over 60 billion procedure per minute .
That ’s ten times faster than current country - of - the - art analog - to - digital convertor , and it mean it ’s capable to find and canvass any signaling at 30 GHz or below . But perhaps most importantly , it can allow “ arrangement to better operate in engorged spectrum bands and to more apace react to spectrum - based threats , ” harmonize to DARPA . In other words , it can deal with electronic warfare attack , where the local electromagnetic spectrum is filled with junk signals to overwhelm organization , so fast that they ’re no longer an issue .
The whole process generate a honestly awe-inspiring terabyte of data every single second . The chip , built in colligation with GlobalFoundries using its 32 nanometer manufacturing process , also contains on - board processing circuitry so that all that datum does n’t have to be passed on to electronics further down the line .
The only downside is that the new chip gobble up power . In the future tense , though , DARPA hopes to apply smaller - ordered series electronic transistor technology , building similar chips using 14 - micromillimetre processes . It ’s hop-skip that should increase efficiency by as much as 50 percent , potentially making the devices portable .
