This section explains how to use the interactive Classical Filter Design Express VI to design floating-point filters and also how to analyze and use a designed floating-point filter.

You first design a filter that meets the target specifications. You then analyze the resulting filter's characteristics to determine if the filter meets the system's requirements. 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.

The following figure illustrates the floating-point filter design process:

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.
