thd calculation
There is thd function in specture calculator., after filling in the function form and I
can print the thd value: 2.283m.
My question is how to use this value to calculate dB?? Does this "2.283m" include %?
1) 2.283m -> 20*log(2.283m) = -52.8dB
2) 2.283m -> 20*log(2.283m %) = -92.8dB
which one is correct???
Thank you very much!
