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, ...
The usual schematic of a state-variable filter with two inverting integrators is well known. Curiously, the input signal is almost always connected to the minus input of U1. Figure 1 is an example ...
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 ...
