在水文工程地质和物探找矿等领域，由于二次场电压受到多种噪声干扰，常规的硬件补偿电路或滤波电路有时无法达到精度和实时处理的要求，甚至增加系统设计的难度和成本。为了解决这些问题，提出并实现将有限冲击响应（ finite im－pulse response， FIR）滤波和快速傅里叶变换（fast Fourier transformation， FFT）应用在需要通过测量二次场电压测明某一区域内视电阻率或视幅频率的分布式激发极化法中。通过Matlab仿真和水槽模型试验模拟和验证了FIR滤波和FFT在激发极化法中的可行性和有效性。

In hydrological engineering geology and geophysical prospecting ,and other fields, due to the second-ary voltage interfered by a variety of noise , however regular hardware compensation circuit or filter circuit ,some-times, cannot suit the requirements of precision and real-time processing, even increase the difficulty of system de-sign and cost .In order to solve these problems .The finite impulse response ( FIR) filter and FFT are put forward in the distributed induced polarization method when need to measure the secondary voltage to know apparent resis -tivity in certain area .Through Matlab simulation and sink model test , the feasibility and effectiveness of the FIR fil-ter and FFT in induced polarization method are verified .
