| Sumario: | A new way of sampling analogue signals, which could overcome many limitations of the uniform sampling method developed in 1948 by Claude Shannon, has been described by Akram Aldroubi of Vanderbilt University in Nashville, Tennessee, and Karlheinz Gröchenig of the University of Connecticut. Although their method is likely to have only a limited effect on day-to-day applications, the technique could revolutionize specific fields such as like body-scanning that demand vast levels of information processing. Aldroubi and Gröchenig believe that they have developed a set of mathematical algorithms that will permit the fast and robust reconstruction of signals from digital samples without the need to worry about band limits or uniform sampling. |
