Floating-Point Filter Design Process (Digital Filter Design Toolkit)

The following figure illustrates the floating-point filter design process. You first design the specifications of the filter. You then analyze the characteristics of the resulting filter to determine if the filter meets the requirements of the system. If the filter does not meet the requirements of the system, you can modify the specifications and repeat the process. After you design an appropriate filter, you can use the filter in the system.

For a particular design problem, you can use several different techniques and filter types to yield an acceptable result. To achieve the best results, you might need to experiment with several different approaches.
