Calculating time in a logarithmic scale

Click For Summary
SUMMARY

This discussion focuses on calculating sample times in a logarithmic scale for automated data recording. The user seeks to understand how to determine the next sample time when starting from an interval of 1 second. Examples provided include sequences such as 1, 2, 4, 8, 16, 32 and 1, 10, 100, 1000, 10000, illustrating the concept of logarithmic sampling. The conversation emphasizes the importance of understanding Z-transforms in relation to this sampling method.

PREREQUISITES
  • Understanding of logarithmic scales
  • Familiarity with Z-transforms
  • Basic knowledge of data sampling techniques
  • Experience with automation in data recording

Hi Everyone,

I have a question about logarithmic sampling. I think I might have to go and review my Z-transforms, but maybe not.

The reason I am doing this is because I am automating equipment which records the data over time, but I want the sampling to be done logarithmically.

If I have an internal of 1s, and I want to sample logarithmically (is that a word?), how do I calculate the next sample time?

Thanks!

You have all the freedom you want, but is it really what you want ?
For example: 1, 2, 4, 8, 16, 32, ... would be equidistant on a time scale that is plotted logarihmically. But so would
1, 10, 100, 1000, 10000, ...
