HGaussian Window. This is the default window function (see Figure 3--53). It
is unique in that the time-domain shape of an exponential Gaussian function
transforms into a Gaussian exponential shape in the frequency domain. This
window provides optimal localization in both the time and the frequency
domain. This is the filter shape most commonly used in spectrum analyzers.
