What is cascaded filter?

Cascading filters allow you to apply a filtering component such as a page filter or an interactive filter widget to other interactive filter widgets.

What happens when you cascade filters?

When you cascade two FIR filters together, the output of the first becomes the input to the second. The order does not matter. Either filter can be placed first, it makes no difference. The final result is the same even though the intermediate results are different.

What is sampling rate of a filter?

The Audio Engineering Society recommends 48 kHz sampling rate for most applications but gives recognition to 44.1 kHz for Compact Disc (CD) and other consumer uses, 32 kHz for transmission-related applications, and 96 kHz for higher bandwidth or relaxed anti-aliasing filtering.
