The package provides a set of LaTeX macros (based on PSTricks)
for plotting the kind of graphs and figures that are usually
employed in digital signal processing publications. DSPTricks
provides facilities for standard discrete-time "lollipop"
plots, continuous-time and frequency plots, and pole-zero
plots. The companion package DSPFunctions (dspfunctions.sty)
provides macros for computing frequency responses and DFTs,
while the package DSPBlocks (dspblocks.sty) supports DSP block
diagrams.
