Previously on The Filter Wizard (“Simulate Circuits in a Spreadsheet with some ‘Ladderal Thinking’ “), we saw how to use a spreadsheet such as Excel to calculate the frequency response of a filter ...

Filter design, be it active, passive, or switched capacitor, is traditionally a mathematically intensive pursuit. There are many architectures and design methods to choose from. Two methods of high ...

This idea details a design method for making anti-aliasing prefilter parameter tradeoffs between several factors. These factors include the filter pass-band magnitude accuracy, the filter order (the ...
