Some problems associated with the application of timespectral analysis to type Pc1 geomagnetic pulsations
Abstract
The investigation of amplitudeduration recordings of geomagnetic pulsations requires timespectral analysis. Two problems associated with the application of this analysis are discussed. The first has to do with the conditions under which the ratio between the partial derivative of omega (the frequency of pulsation) and the partial derivative of the moment of time corresponding to the maximal amplitude of the timespectral diagram coincides with delta t  the width of the output signal envelope at frequency omega. The second problem has to do with finding two parameters on the timespectral diagram for the real part of the function which approximates the pulsations.
