We consider the problem of optimizing signal transmission through multichannel noisy devices. We investigate an array of bithreshold noisy devices which is connected in parallel and convergent on a summing center. Utilizing the concept of noise-induced linearization we derive an analytical approximation of the normalized power norm and clarify the relation between the optimum threshold and the ...

Commonly used sums-of-squares-based error or deviation statisticsdlike the standard deviation, the standard error, the coefficient of variation, and the root-mean-square errordoften are misleading indicators of average error or variability. Sums-of-squares-based statistics are functions of at least two dissimilar patterns that occur within data. Both the mean of a set of error or deviation magn...

The nonlinear propagation of a pure sinusoid is considered using time domain statistics. The probability density function, standard deviation, skewness, kurtosis, and crest factor are computed for both the amplitude and amplitude time derivatives as a function of distance. The amplitude statistics vary only in the postshock realm, while the amplitude derivative statistics vary rapidly in the pr...
