Digital Filter Design/Digital Filter Design Lite
The Digital Filter Design tool for the dsPIC
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
filter transfer function is supported with multiple generated
graphs, such as: magnitude, phase, group delay, log
magnitude, impulse response and pole/zero locations.
Finite Impulse Response Filter Design
• Design method selection:
• Low-pass, high-pass, band-pass and band-stop filters
• FIR filters can have up to 513 taps
• Following window functions are supported:
• Reports show design details, such as window
• Filters are designed for a maximum gain of 1
