Digital Filter Design/Digital Filter Design Lite
Summary
The Digital Filter Design tool for the 16-bit dsPIC30 and
dsPIC33F/E Digital Signal Controllers (DSCs) 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 generates
the filter code and coefficient files ready to use in the
MPLAB®IDE Integrated Development Environment. System
analysis of the filter transfer function is supported with
multiple generated graphs.

Various window functions are supported:
Reports provide design details such as window
coefficients and impulse response prior to multiplying by
the window function
