摘要 从简化了的ARMA谱估计计算公式出发,推导出ARMA谱分辨相邻谱峰的频率分辨力与采样频率和ARMA模型阶数的关系,指出了ARMA谱分辨相邻谱峰时的有效频率区间和盲区。 Based on the sirnplified expression of estimation for the ARMA spectrurn,the relation-ship between the frequency resolving power to distinguish the adjacent peaks of ARMA spec-trum, the sampling frequency and the order of the model of ARMA spectrum is derived. Theeffective frequency range and the blind region in distinguishing the adjacent peaks of ARMAspectrum are given.
