How to calculate THD using calculator?

greatqs

I found the thd() in calculator only has  5 arguments (e.g. from, to, # samples, fundamental frequency).

For example, I'm doing a FFT with sample frequency of 8192KHz with from=1ms to=2ms and fundamental frequency is 5KHz.

I want to calculate the THD within 20 ~ 20KHz instead of 0 ~ 4096KHz which thd() does since it doesn't include Fmin/Fmax arguments.

 

Thanks,

qs

  • Your first post appeared at just before 6pm my time, and second after 10pm, having broken the forum guidelines and posted on an old thread. It wasn't clear which of the two questions in this thread you were asking, but given that this forum is covered by Cadence folks in their spare time (and I do have a life outside of work), being quite so pushy is a bit unreasonable. 

    If it is urgent, you should go to customer support at support.cadence.com

    If not I will look into this once I'm back from being on vacation tomorrow.
