摘要：

A simple design method is proposed for square root domain filters. The method is based on the imitation of passive filters (or their signal flow graphs). This allows square root domain topologies and parameters to be easily extracted. The method is augmented by a simple method to study and manipulate the filter's DC point. The method is used to design a universal biquad filter as a demonstration of its applicability.
