How to know the order and coefficients of a new cascaded filter?

Hello everyone :)

I have 3 serial filters and I want to generate one cascaded filter. I used dfilt.cascade command in Matlab. How can I check the order and the new coefficients of the new filter?

The Matlab code is:

%%%%%%%%%%%%

num1=[1 0 0 0 0 0 -2 0 0 0 0 0 1];

den1=[1 -2 1];

low=dfilt.df2(num1,den1);

num2=[-1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 32 -32 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1];

den2=[1 -1];

high=dfilt.df2(num2,den2);

num3=[-1 -2 0 2 1]/8;

dif=dfilt.dffir(num3);

% Cascaded Low,High, and Differentiator filters

Hcas=dfilt.cascade(low,high,dif);

%%%%%%%

I need to know the order and coefficients of Hcas filter.

Thanks in advance
