In signal processing,a lot of signals in real situation are often associated with noise.In order to eliminate or reduce the influence of noise,extract useful signals,we should filter them.The system which can filter the signals is known as filter.In this paper,the author presents a direct method to design filter: zero-pole cumulative test method.The paper not only introduces the thought and steps of designing it by using zero-pole cumulative test method,but also gives a simulation based on matlab.Because under the circumstance of random disturbance,how to recover the true signals is one of the most important problems in signal processing,the method proposed in this paper has extensively application in data processing,image processing and network communications.
