Hilbert Space Theory

Module by: Phil Schniter. E-mail the author

Hilbert spaces provide the mathematical foundation for signal processing theory. In this section we attempt to clearly define some key Hilbert space concepts like vectors, norms, inner products, subspaces, orthogonality, orthonormal bases, and projections. The intent is not to bury you in mathematics, but to familiarize you with the terminology, provide intuition, and leave you with a "lookup table" for future reference.

Definition of a lens

Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
