• ### Compressive Sampling and Frontiers in Signal Processing

One of the central tenets of signal processing and data acquisition is the Shannon/Nyquist sampling theory the number of samples needed to capture a signal is dictated by its bandwidth. Very recently an alternative sampling or sensing theory has emerged which goes against this conventional wisdom. This theory now known as "Compressive Sampling" or "Compressed Sensing" allows
