摘要：

This brief presents novel low-complexity designs of rectifying encoders for direct processing of the first-order delta-sigma modulated pulse streams. The first solution consists of a D flip-flop and an XOR gate. The second solution incorporates a sign detector. Our results are compared and contrasted with theory and with results found in the literature such as waveform shapes and signal-to-noise ratios. Analytical models, numerical simulations, and experimental measurement results are presented.
