Essay

Using Standardized Gaussian PRNG to generate Gaussian noise with specified variance.The following work sheet specifies the noise variance σN2\sigma _ { \mathrm { N } } ^ { 2 } in A2.Using the standardized Gaussian random numbers generated in Column B form the random noise values having the specified variance in Column C.
a.What is the formula that computes the noise SD in B2?
b.What is the formula in C5?
