Triangular, Window Functions, Noise
Extensive DSP Functions – FFT, DCT, Filtering,
Convolution, Interpolation
Extensive Arithmetic Functions – Algebraic
Expressions, Data Scaling, Clipping, etc.
1-D, 2-D and 3-D Displays
Multiple Data Quantization and Saturation
Options
Multi-Channel Data Support
Automatic “Script File”-based Execution Options
available for any user-defined sequence of
dsPICworks Tool Functions
File Import/Export interoperable with MPLAB IDE
Digital Filtering Options support Filters generated
by dsPIC DSC Filter Design
ASM30 Assembler File Option to export Data
Tables into dsPIC33F RAM
