Multiple feedback topologyis an electronic filter topology which is used to implement anelectronic filterby adding two poles to thetransfer function. A diagram of the circuit topology for a second order low pass filter is shown in the figure on the right. Analog filters and specifications swimming...
Low-passfilters are commonly used to implement antialias filters in data-acquisition systems. Designof second-order filters is the main topic of consideration.Filter tables are developed to simplify circuit design based on the idea of cascading lower-order stages to realize higher-order filters. ...

PURPOSE:To form a filter having a different frequency characteristic by providing an amplifier to the post stage of a low-pass filter in an active filter circuit used for an audio equipment and applying a control signal to control the feedback quantity to a feedback circuit of the amplifier....
An active RC all-pass filter (12) is connected to the output of low pass filter (10). At least two poles of the filter circuit lie at the frequencies to be damped. The low-pass filter has preferably a passive first-order low pass filter (14) connected at its input (34)....
In this situation, the Sallen-Key active filter can save the day. This circuit implements a 2-pole filter. Cascading several stages can give you a steep attenuation curve with a very sharp knee. LOW-PASS FILTER DESIGN Although there are many filter types and ways to implement them, here’...
