spec.pgram() normalized too what?
...oo sum to EXACTLY too some normalization of the discrete signal a[], and the word "estimate" should come into play only when making inferences about the real signal 'a' that the discretely sampled signal came from. >a <- sin(2*pi*(0:127)/16) >N <- length(a) # 128 >PSD <- spec.pgram(a, spans=NULL, detrend=F) ## Sum Squared amplitude of a[t] on [0, 127]. >sum(abs(a)^2) [1] 64 ## Mean Squared amplitude of a[t] on [0, 127] sum(a^2)/N [1] 0.5 By Parseval's theorem, the integral of the one-sided PSD over zero and positive frequencies should equal the mean...

[Bug 78] -m psd -j TARPIT returns all ports open from nmap
https://bugzilla.netfilter.org/cgi-bin/bugzilla/show_bug.cgi?id=78 ------- Additional Comments From tools@die.net 2003-04-17 15:47 ------- Showing any ports open that are sent to it is the normal function of TARPIT target. The psd match will start routing all ports to it after it decides that an IP is portscanning, so this is the expected behavior. That being said, the psd match won't route any TCP ACK packets to the specified target. It seems to be trying to do this to keep from affecting outgoing connections, but its...

Relating Spectral Density to Chi-Square distribution
Dear list, I had some confusion regarding what function too use in order too relate results from spec.pgram() too a chi-square distribution. The documentation indicates that the PSD estimate can be approximated by a chi-square distribution with 2 degrees of freedom, but I am having trouble figuring out how to do it in R, and figuring out what specifically that statement in the documentation means. I have very little exposure to distribution functions in R. I have started w...

How do I normalize a PSD?
...spec.pgram(), use the smoothing kernel to get a better estimate at the frequency centered in the bandwidth. If your frequency bin of interest is wider than the bandwidth of the kernel, average across frequencies (I think). The estimate appears to be normalized already. If you are calculating your PSD independently, then oversample (e.g. 2, perhaps 4 or more times the highest frequency you need to characterize, and sum (not average) across the frequency bin to get the power estimate of the center frequency in that bin. Shove the whole signal into memory and don't window it if you can. The ov...
