Re: ¡°Fixture In A Hurry¡±. And a Transformer.
Use 20Log for voltage ratios and 10Log for power ratios. This video of mine might help: https://www.youtube.com/watch?v=1mulRI-EZ80

Use 20Log with voltage ratios and 10Log for power ratios. Maybe this video will help: https://www.youtube.com/watch?v=1mulRI-EZ80

Re: Test do not read
I wrote the test message. I had made my first post, but I could not see it. I made the second test post to see if that would go through. When I posted the test post, I saw the note that it would be

Re: ¡°Fixture In A Hurry¡±. And a Transformer.
So when is it 20log and when 10log? I think 10log for power and 20 log for magnitude? John
