Abstract :
This paper introduces a system for reconstructing a class of nonuniformly sampled and decimated bandlimited signals. This system makes use of a number of real-valued multipliers and one digital filter. One advantage of the new system is that it easily can achieve perfect reconstruction in the whole frequency band. A drawback is that it requires that the signals be oversampled by a factor that exceeds the theoretical value
