      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.

Module by: Melissa Selik, Richard Baraniuk Translated by: Fara Meza, Erika JacksonBased on: Table of Common z-Transforms por Melissa Selik, Richard Baraniuk

Summary: Lista transformadas-z y ROC para varias señales discretas.

La siguiente tabla provee transformadas de z unilateral y bilateral. Esta tabla también muestra la región de convergencia.

note:

la notación usada para z z en esta tabla puede ser diferente a la notación encontrada en otras tablas. Por ejemplo la transformada básica de un u n se puede describen de dos maneras diferentes, que son equivalentes:
zz-1=11-z-1 z z 1 1 1 z -1 (1)
