Can you cascade filters?

Filters in either area can be grouped in a cascade set. Filters in a cascade set can affect selections for other filters in the set. Filters in a cascade set can affect each other in two possible ways: First to last or Multidirectional. You can create one cascade set in an area for each data source.

What happens when two low pass filters are cascaded?

When two filters are cascaded, the transfer function of the resulting filter is the product of the transfer functions of the individual filters. For example, an ideal bandpass filter can be constructed from a cascade of an ideal lowpass filter and an ideal highpass filter with overlapping passbands.

How do you combine two FIR filters?

Adding the Outputs of two FIR Filters

An informative experiment is the following: Filter the signal with low-pass filter. Then filter the original signal with a special high-pass filter having the same cutoff frequency (called a complementary filter). Now when you add up the two results, you get original signal back!
