It is seen that part of the spectrum in the range of 15-50 [cm.sup.-1] is linear in a logarithmic scale; hence the dependence of the density of states on frequency is described by a power function g(v) ~ [v.sup.[alpha]].

In the first edition of the Trends book, the logarithmic scale was still used but a separate version of the trends with Cartesian coordinates was also provided.
The drawback of SNR observables is that they are reported in logarithmic scale (in dB), their resolution is in some cases limited as they are rounded to 1 dB, and the value of SNR is receiver depended, according to the applied code correlation technique (Hoffmenn-Wellenhof et al., 2001).
In Figure 4, we plot the error as functions of m, where a logarithmic scale is used for the spatial-error-axis.
