What approximation techniques exist for the square super-root function?
I need to implement an approximation to the inverse of $x^x$, i.e. the square super-root (ssrt) function. For example, $\mathrm{ssrt}(2) \approx 1.56$ means that $1.56^{1.56} \approx 2$. I'm not as interested in any particular accuracy/bit-depth as…

Amount of exactly approximated samples with Padé approximation
I've already had some good discussion with Fat32 in this question yesterday.
Today I'm confused again. The author of Statistical digital signal processing and modeling M.h. Hayes and Fat32 both stated that Padé can approximate p+q+1 samples. Then I…

How to combine similar signals to generate another one?
Assume there are 11 signals. These signals are very similar to each other in both time and frequency domains. (And the similarity between them is not random; they are similar because they have somehow a common source. Actually they are…
