Artificial neuarl network is one of the recent developed softcomputing technique work on the basis of human neural system. The traning and testing are the two important process in artificial neural network. ther are many techniques used for the training of artificial neural network, however backpropagation algorithm is the traditional method for training purpose. this document contain the mathematical formation of artificial neural network with backpropagation training.

说明：   , =2π, =1/2π,取采样周期 =π/2, =2/π=4 满足采样定理： ,N=5,10,20。 比较 与 。(, = 2π, = 1/2π, take the sampling period = π/2 = 2/π = 4 satisfy the sampling theorem: N = 5,10,20. Compare with.)
