SW300001

The SW300001 is a Digital Filter Design tool for the dsPIC 16bit digital signal controllers makes designing, analyzing and implementing finite impulse response (FIR) and infinite impulse response (IIR) digital filters easy through a menu driven and user intuitive interface. The filter design tool performs complex mathematical computations for filter design, provides superior graphical displays and generates comprehensive design reports. Desired filter frequency specifications are entered and the tool automatically generates the filter code and coefficient files ready to use in the MPLAB integrated development environment (IDE). System analysis of the filter transfer function is supported with multiple generated graphs such as magnitude, phase, group delay, log magnitude, impulse response and pole/zero locations.

• Design method selection, FIR windows design or FIR equiripple design
• Lowpass, highpass, bandpass and bandstop filters
• FIR filters can have up to 513 taps
• Reports show design details
• Generated files are compliant with the dsPIC30F C30 compiler, assembler and linker
• Magnitude response vs. frequency graphs
• Choice of placement of coefficients in program space or data space
• C wrapper/header code generation
• Digital transformations are performed by bilinear transformation method
• Lowpass, highpass, bandpass and bandstop filters
