Joseph Pathikulangara
Joseph Pathikulangara is an engineer with the CSIRO, an Australian Government research organisation, from 1995 onwards. Before this, he was an engineer with DRDO, India for about 11 years.
At CSIRO, he has built Signal Processors and Software Defined Radios of various forms and shapes for several projects and application spaces. At present he is at the Space & Astronomy business unit focusing on Radio Astronomy Instrumentation.
He has a BE in Electronics and Communications from the IISc, Bangalore and M.Tech in Computer Science and Engineering from IIT-Bombay.
Multi-Nyquist Sampling Technique and Signal Reconstruction
Status: Not yet available - Stay tuned!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.
