Abstract

The extraction of spectral density and correlation functions from vibration and acoustic signals, etc., has been undergoing a continuing process of refinement. This refinement has been brought about by more and more stringent analysis requirements. The design of improved analyzers to meet such requirements has been going on concurrently. Usually the signals to be analyzed are played back from magnetic tape recorders. The flutter of the tape transports involved can degrade or effectively destroy such possible desired parameters as high resolution, high dynamic range, extreme accuracy of analysis, etc., for either spectral density or correlation function plots. Formulae are developed to show how both sinusoidal and random components of flutter introduce error into the analysis, and to indicate how flutter limits the range of useable values of spectral resolution, correlation time-delay, etc. The pertinent features of a tape transport, the influential characteristics of its flutter, etc., are also discussed. Suggestions are also given regarding the interpretation of the data on transport flutter that is usually available.

带输运颤振对频谱及相关分析的影响

从振动和声信号等中提取谱密度和相关函数，一直在经历一个不断改进的过程。这种细化是由越来越严格的分析需求带来的。为满足这些要求而改进的分析仪的设计一直在同步进行。通常要分析的信号是从磁带录音机中回放出来的。无论是谱密度图还是相关函数图，所涉及的磁带传输的颤振都会降低或有效地破坏诸如高分辨率、高动态范围、极高分析精度等可能需要的参数。推导了颤振的正弦分量和随机分量如何在分析中引入误差的公式，并指出颤振如何限制频谱分辨率、相关时延等可用值的范围。讨论了带式输运的相关特性及其颤振的影响特性等。对通常可用的输运颤振数据的解释也提出了建议。
