Filters are used in many applications to remove unwanted frequency components from incoming signals, enhance incoming signals, or both. In portable and non-portable medical applications, for example, ...

Set up, test and tweak this filter in PartSim to see it’s behavior before building it. The state-variable realization offers the most precise implementation at the expense of many more circuit ...

A new generation of wideband amplifiers and multipliers allows you to build state-variable active filters that operate beyond the kilohertz region into the megahertz region. Using these devices and ...
