Summary
The Digital Filter Design tool for the dsPIC®16-bit 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 intuitive user
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.
