[QUOTE="BJ James, post: 57908, member: 87"] Re: help with hz to octave conversion for dsp ok, Math is not my strong suit so I used the calculator to get the same results. So Q is fc divided by w. I punch Q in the conversion to find octave bw and I get a reasonable looking number. Here's what's messing with me. The first filter Yorkville lists for my boxes is 205f, -6 dB, 5hz w. I punch the numbers into the magic box and i get a q of 41 = octave bw of .0352. That just doesn't seem right and my dsp certainly doesn't provide that tight a filter. I'll probably give Yorkville another call, but I'd still like to understand this a bit more. Also, i did try to do a TF in smaart but i am really new to it and don't trust what I'm seeing. But that is for another forum to help me with. Thanks, BJ [/QUOTE]
