摘要

In order to realize a discrete-time filter for wideband signal processing, a new finite impulse response filter (FIR) has been developed. The filter maintains the moving average effect, but the decimation function is removed in order to realize a cascadable filter. By cascading the proposed FIR filter with a conventional FIR filter, about -60 dB attenuation across 50 MHz signal bandwidth is possible, and by the cascade more stages, the bandwidth can be even wider. This bandwidth is wide enough to process the signals of the next generation systems, opening up the way of utilizing the sampling receiver.
