SUMMARY

The plot discussed represents a transfer function that is identified as a 2nd order high-pass filter. The function plotted is 1 - e-x, which illustrates an exponential decay in a log-log scale. The discussion also highlights the unusual vertical axis labeling, where each set of 10 logarithmic lines increases by a factor of 100 instead of the expected factor of 10. This discrepancy raises questions about the accuracy of the axis representation.

PREREQUISITES
  • Understanding of transfer functions in control systems
  • Familiarity with exponential decay functions
  • Knowledge of log-log scale plotting techniques
  • Basic concepts of high-pass filter design
NEXT STEPS
  • Research the characteristics of 2nd order high-pass filter transfer functions
  • Explore the mathematical properties of exponential decay functions
  • Learn about log-log scale plotting and its applications in data visualization
  • Investigate common issues with axis labeling in graphical representations
USEFUL FOR

Engineers, physicists, and students in signal processing or control systems who are analyzing transfer functions and their graphical representations.

Hey all

What's could the function be on the plot (see the attachment)?

I know! I know! Pick me! :smile:

Where did you get it, and what do you think it is?
 
For some reason your response led me to think that the answer is obvious... :biggrin: So I plotted 1-e^{-x} and it turns out that it's the answer I'm looking for. Never seen an (inverse or whatever it's called) exponential decay plot in log-log scale before ..
As for the irrelevant 'where did you get it' -- it's thermally averaged cross section.

Glad I could help :smile:

To me it looks like a 2nd order high-pass filter transfer function. The vertical axis does look strange, though. How come each set of 10 logarithmic lines on the vertical axis is x100 instead of x10? Is that on purpose? What would the labels for each of the 10 minor gridlines be on the vertical axis...?
