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 ...

Analog variable frequency filters require the use of variable passive components. The higher the slope of the filter, the greater the number of needed variable passive components. These elements are ...
