A Multiplierless DC-Blocker for Single-Bit Sigma-Delta Modulated Signals

A Multiplierless DC-Blocker for Single-Bit Sigma-Delta Modulated Signals

The DC content in single-bit domain is both undesirable and hard to remove. In this paper we propose a single-bit multiplierless DC-blocker structure. The input is assumed to be sigma-delta modulated bitstream. This DC-blocker is designed using a delta modulator topology with a sigma-delta modulator...
