Engineering Analysis/MISO Transformations

Consider now a system with two inputs, both of which are random (or pseudorandom, in the case of non-deterministic data). For instance, let's consider a system with the following inputs and outputs:

• X: non-deterministic data input
• Y: disruptive noise
• Z: System output

Our system satisfies the following mathematical relationship:

$Z=g(X,Y)$

Where g is the mathematical relationship between the system input, the disruptive noise, and the system output. By knowing information about the distributions of X and Y, we can determine the distribution of Z.
