I am looking for references regarding the calculation of system error.

Assuming that the errors of each component in the system is random, I assume

that we can use a formula including the variance of each component, such as:

Etotal = sqrt( E1^2 + E2^2 + ... + En^2)

However, I cannot find a good reference, which states clearly the formula

used to calculate the system total error. Can anyone help?

Thank you.
