So, going forward, we need the power and voice of UGC news, as well as the curatorial tools and fact checking chops of working Journalists to help us filtersignal from noise.
The breakthrough came when researchers found that radios could be tweaked to filter out the signal from its own transmitter, something that already happens within noise-canceling headphones.
These short-term assignments must get done fast--designing filter algorithms for digital signal processors, say, or writing software for Internet-based phone calls.
The superconductor's lack of resistance allows the firm to build filters that can chop a signal into much narrower frequency bands than a traditional filter.
