(SIN X)/X Interpolation of Sampled Signals

Abstract

A method for (sin x)/x interpolation of sampled signals is described. The method works by transformation to the frequency domain and therefore requires a digital computer with Fast Fourier Transform capability. Examples of how the (sin x)/x interpolation can be used for signal reconstruction and in connection with beam-steering are presented. The practical implication of this method for (sin x)/x interpolation is that it allows the use of a sampling frequency that is lower and closer to the theoretical minimum than would otherwise be possible. The complexity and cost of the electronic system used for sampling and recording can thereby be reduced.
