With rapid advance in analogue‐to‐digital converters, more analogue‐to‐digital converters in the market can cover multiple Nyquist zones. As a result, the implementation of a sub‐Nyquist receiver designed to cover a bandwidth wider than what is dictated by Nyquist theory has become more feasible than ever. This article presents a sub‐Nyquist receiver using both different sampling rates and an offset at sampling instant. Compared with other sub‐Nyquist receivers, the proposed design is straightforward to implement and can avoid issues conventional sub‐Nyquist receivers encounter at the presence of multiple signals.
