Abstract
The spectral analysis of a long time series is often hampered by the limited capacity of the Fourier analyzer. The ideal frequency resolution of the analysis of N sample points cannot be realized if the analyzer cannot handle N points simultaneously. This paper examines some of the aspects of the zoom transform, which provides for partial recovery of the ideal resolution on an analyzer of limited capcity by concentrating the analysis on selected frequency bands.
