Fig. 6.

Broad peak widths require large resampling factors. a) Upper panel: Similar as in Fig. 5a) but with increasing peak widths from left to right. Note that removal of peaks from the aperiodic component (grey) worsens with broader peak widths. Lower panel: The lower fitting range border is on the x-axis, the absolute deviation from the ground truth on the y-axis. The 1/f exponent estimation error increases with larger peak widths. b) Simulation of a 30 Hz and 300 Hz peak with increasing peak widths from left to right. Larger peak widths require larger resampling factors. Note that not the absolute peak width but rather the logarithmic peak width $\mathrm{\Delta }{f}_{\mathit{log}}$ determines the minimum resampling factors
