摘要
讨论了在Sharp MZ-3500微机上计算偏相干函数的方法,并用此法对小轿车的噪声源进行了监测和识别.最后分析了噪声识别的测量误差。
Discusses the method of calculation of the partial coherence function, making use of a Sharp MZ -3500 micro-computer. With this method, noise sources on cars are measured and identified and the measurement errors in noise identification analyzed.
