Abstract :
In this paper, a single-bit DC-blocker is presented. It is comprised of a ternary filtering stage preceded by a sigma-delta modulator. Different techniques are used to generate the ternary taps for hardware and performance optimization. Both the input and the output of this DC-blocker are assumed in single-bit format. The proposed DC-blocker can easily be implemented with FPGA.
