Discussion Overview

The discussion revolves around identifying the type of transfer function represented by a plot shared in the thread. Participants explore various interpretations of the plot, including its mathematical representation and characteristics, while considering its application in a specific context.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that the function could be represented by the equation 1-e^{-x}, indicating it resembles an exponential decay plot in log-log scale.
  • Another participant proposes that the plot looks like a 2nd order high-pass filter transfer function, questioning the vertical axis scaling and the labeling of the logarithmic lines.
  • There is a mention of the plot being related to a thermally averaged cross section, although the relevance of this context is debated.

Areas of Agreement / Disagreement

Participants express differing views on the interpretation of the plot, with no consensus on the exact type of transfer function it represents. Multiple competing interpretations remain unresolved.

Contextual Notes

Participants raise questions about the vertical axis scaling and the labeling of gridlines, indicating potential ambiguities in the plot that may affect interpretation.

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...?
