I feel like this is an inverted interpretation? Transmission tech uses those methods because the math shows the desired properties.

Linear algebra is used everywhere, orthogonalization, SVD, eigenvalues etc are valuable because the resulting properties are very useful in many places.

Yea, I could have used a better word choice. I was thinking about the domains here in the generalized sense such as signal processing and wireless communication being applicable to the domain of artificial intelligence. In reality, you are correct that it's all tied together under of domain of applied maths or computer science.
