摘要

本文给出了两类复滤波器的近似，一类只有复极点，另一类既有复极点又有零点。这些复系数滤波器的近似是基于曲线拟合技术，其中滤波器的幅度响应近似为有理整阶传递函数。通过MATLAB仿真验证了所提出的逼近方法，并使用现场可编程模拟阵列（FPAA）器件进行了实验验证，该器件具有数字可编程性。

Approximation of complex coefficient filters

This work presents approximations of two classes of complex filters, those with complex poles only and those with both complex poles and zeros. The approximation of these complex coefficient filter is based on a curve-fitting technique, where the magnitude response of the filters is approximated to a rational integer-order transfer function. The proposed approximation method is validated through MATLAB simulations and is experimentally verified using a Field Programmable Analog Array (FPAA) device, which offers digital programmability.
