A slight improvement to 14.6 dB S/N when I apply a 40 degree phase *lag* to the 20:00 to 00:00 signal. http://abelian.org/vlf/tmp/170326b.png The phase lag and duration of it are optimum. -- Paul Nic
It is. I'm simply adding the daily signals in the time domain. A box car averaging with a repetition period of 24 hours. The signal (hopefully) adds coherently to sum to 9 times the average amplitude
Hello Paul, ULF, Thank you for working out the signal so clearly. The accurate frequency matching is an ID in itselfe. Most impressing. It was an exciting and unique experiment taking months from the
I'm thinking about suggesting a smaller CRC and therefore a shorter list length, with the stronger codes, for example http://abelian.org/ebnaut/calc.php?sndb=14&snbws=0.000025&snmps=&code=16K25&sp=36
Indeed, it would be extremely unlikely to get a peak at exactly that frequency, especially as you've chosen a non-integer frequency. A remarkable achievement. I doubt that many will want to put in th
Paul, Thanks for your reply below. In available time I'm trying to verify that FDTD can be helpful for the ULF tests (and vice versa, that the ULF experimental results can validate FDTD for ULF). So
Hello Jim, Can you extend that plot to 1E-1...1E1 kHz? 73, Stefan Am 07.06.2017 03:07, schrieb [email protected]: Paul, Thanks for your reply below. In available time I'm trying to verify that FDT
Stefan, Yes, working on a 1E-1 to 1E1 Hz plot now. Very interested in what FDTD thinks 1E-1 to 1E0 kHz looks like. Guessing 1E-1 to 1E0 Hz will be smooth but even in that case it's hard to guess at w
