my professor gave me this equation to compute the distribution of the noise signal but I have no ideal what it is, so can someone explain this for me
1/√(2πσ)*e^((x-μ)^2/2σ^2 )

thanks

IIRC, that is the probability density function of a normally distributed random variable with mean μ and standard deviation σ. But I could be wrong.
