      Lenses

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

      What is in a lens?

      Lens makers point to Connexions 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 Connexions member, a community, or a respected organization.

Resampling with Rational Factor

Module by: Phil Schniter

Summary: Describes the process of resampling, or sample-rate conversion.

Interpolation by LL and decimation by MM can be combined to change the effective sampling rate of a signal by the rational factor LMLM . This process is called resampling or sample-rate conversion. Rather than cascading an anti-imaging filter for interpolation with an anti-aliasing filter for decimation, we implement one filter with the minimum of the two cutoffs πLπML M and the multiplication of the two DC gains (LL and 11), as illustrated in Figure 1.
