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.
