Announcement text: ---------------------------------------------------------------------- This package is a collection of useful macros for disciplines related to signal processing. It defines macros for plotting a sequence of numbers, drawing the pole-zero diagram of a system, shading the region of convergence, creating an adder or a multiplier node, placing a framed node at a given coordinate, creating an up-sampler or a down-sampler node, sequentially connecting a list of nodes, and connecting a list of nodes to one node using any node-connecting macro. ----------------------------------------------------------------------
This package is located at http://tug.ctan.org/tex-archive/graphics/pstricks/contrib/pst-sigsys .
