In the upper diagram, there are two cascated filters. Than how can i get the result 'y(n)' in time domain. In other words , how to express y(n) with the given 2-group parameters. The difficult for me is how to deal with the relationship between the two cascated filters. And I also know the difference equation should be as follows:
But how to derive it from the parameters of the 2 cascated filters . Thanks!
