Amplitude analysis of discrete VLF emissions using the Rayspan spectrum analyzer showed characteristics that are not readily detected using the conventional 'frequency' spectrograms. From a small sampling of discrete VLF emissions recorded at various ground stations, the following observations were made: Rise and fall times may be as small as 15 - 20 msec; Emissions that appear 'single' on a frequency spectrogram may consist of closely-linked shorter emissions, each having a duration of the order of 100 msec; Frequency modulation, previously suspected in some frequency spectrograms, is confirmed. In the samples studied the frequency of modulation ranged from 35 Hz to 70 Hz, while the frequency deviation lay mainly in the range 25 Hz to 50 Hz. (Author).

Open a Window into the Autonomic Nervous SystemQuantifying the amount of autonomic nervous system activity in an individual patient can be extremely important, because it provides a gauge of disease severity in a large number of diseases. Heart rate variability (HRV) calculated from both short-term and longer-term electrocardiograms is an ideal win

The use of standard techniques for measuring the power spectra of stationary phenomena in the treatment of nonstationary physical phenomena can lead to erroneous results. Some of the tools available for the analysis of nonstationary random phenomena are outlined in this report and the applicability of these tools to some practical engineering problems is discussed.
