描述
A simple spreadsheet can be used to help choose parameters. An example is this Anti-Aliasing Filter Tool for Data Converters. This is a Microsoft Excel spreadsheet that allows users to enter the converter resolution, sample rate, and order of filter. Then, view a graph which shows the response of the filter at an assumed 20 dB/decade rolloff per pole, and the aliased spectrum around the sample rate. Where the two lines cross, aliasing will occur. If it is below the resolution and frequency range of interest, all is well. If not, experiment with the cutoff frequency and number of poles to quickly find an acceptable combination. With these parameters chosen, the user can design the active filter using a tool like FilterPro™.
