Multi-Nyquist Sampling Technique and Signal Reconstruction
Joseph Pathikulangara
A new technique for sampling and reconstructing signals has been developed, allowing for the direct sampling of bandwidths much larger than the Nyquist bandwidth. This method, which can produce useful spectral measurements under specific conditions and applications, has been demonstrated in a built system. The system uses analog-to-digital converters (ADCs) sampling at 3 GHz, followed by DSP techniques to reconstruct an impressive 30 GHz of bandwidth—20 times the Nyquist bandwidth.
