Abstract

It has been shown that, using an undersampling technique, it is possible to increase dynamic range, decrease power consumption and costs, and also achieve a more efficient hardware implementation. Yet, the same information is obtained as when using a standard sampling rate, which would require several MHz instead of kHz. As an extra bonus, out-of-band components are reduced, contributing to the increased dynamic range. The technique is not new, but common misconception and the fact that maximum frequency is often mistaken for bandwidth when determining the sampling rate, has led to this technique being rarely used for this and similar types of applications.
