Two new DSP teaching tools: DigiFilter and DSPlus

Two window-based new digital signal processing (DSP) software packages, namely, DigiFilter and DSPlus are used as teaching tools at California State University, Long Beach (CSULB), DSP laboratory in conjunction with DSK31 of TI. First, DigiFilter is a digital filter design and processing software. The uniqueness of this package is that it is not only design digital filters, but also supports DSK31 for real-time filtering. Second, DSPlus is a data acquisition and processing software which supports DSK31 for real-time FFT and can be used as a digital scope. These two packages are employed as computer-aided design and analysis tools for DSP courses.
