  • We present a filter that estimates the signals at time Tm=T(n+1/2), where T=1/fs. Then two filters are needed, one I- and one Q-filter. There exists a class of transversal filters that can be implemented in the sampling unit as an analog filter. The filtering is done in the sampling operation, and by decimating the signal to the base band the A/D conversion can be done at low speed. We have investigated the quality of an implementation in a double-metal single-poly 0.8 /spl mu/m CMOS-process.
