Method for Wideband Signal Digitizing and their Real-time Reconstruction in Enlarged Dynamic Range

I. Bilinskis, K. Sudars, M. Min


Various approaches to signal digitizing and real-time reconstruction in wide frequency and dynamic ranges are considered. They are discussed and compared on the basis of MATLAB simulation results. It is shown that the best results can be achieved at combination of pseudo-randomized sampling of the original signals at sub-Nyquist rates with low bit-rate pseudo-quantizing of the signal sample values obtained at high-frequency periodic sampling.
