Digital Signal Processing is in some kind applied mathematics. Discussed only on paper, this dry stuff it is not so easy to understand for beginners. DSPlay 3.03 gives you the possibility to "play" with sequences, filters and transforms, to experience quickly, what happens if algorithms are applied to signals. And, if the result is not what you expected, to ask new questions and to learn more.
DSPlay 3.03 is distributed as freeware. Please consult the DSPlay general public licence. DSPlay has been developed an educational tool for the course "Digital Signal and Image Processing". No manual is delivered, please consult the online help.
There may still be some bugs in the program, but unfortunately, we cannot supply any support.

大意是说,为了教学而设计,减少数学上的难度,提高实际对数据处理能力等等
