dc.description.abstract	The Report describes an analyser which was developed for finding the power spectra of waveforms derived from vibrating axial compressor blades due to random excitation. The bandwidth of the instrument goes down to about 0.04 c.p.s. The standard deviation of the results is considered in some detail, and it is shown that long samples of data are required in order to get reasonably accurate results.	en_US
