Fiber Bragg Grating Wavelength Demodulation Algorithm
A demodulation algorithm is vital for a fiber Bragg grating (FBG) sensing system. In this paper, a novel demodulation algorithm based on the variable-step-size method and cross-correlation algorithm is proposed to demodulate the wavelength of an FBG. The characteristic feature of these sensors is that the position of the spectrum changes due to the action of a particular physical quantity.

Algorithm from distribution box to distribution box
The Box–Muller transform is commonly expressed in two forms. The basic form as given by Box and Muller takes two samples from the uniform distribution on the interval (0,1) and maps them to two standard, normally distributed samples.OverviewThe Box–Muller transform, by and, is a method for generating pairs of, standard, (zero,. Suppose U1 and U2 are independent samples chosen from the uniform distribution on the (0, 1). Let and Then Z0 and Z1 are random variables with a. The polar form was first proposed by J. Bell and then modified by R. Knop. While several different versions of the polar method have been described, the version of R. Knop will be described here because it is the mo.
