If we consider a sequence of FIR filer with system function Hm(z)=Am(z), then what is the definition of the polynomial Am(z)?

1+∑mk=0αm(k)z−k

1+∑mk=1αm(k)z−k

1+∑mk=1αm(k)zk

∑mk=0αm(k)z−k

What is the unit sample response of the mth filter?

hm(0)=0 and hm(k)=αm(k), k=1,2…m

hm(k)=αm(k), k=0,1,2…m(αm(0)≠1)

hm(0)=1 and hm(k)=αm(k), k=1,2…m

none of the mentioned

What is the output of the single stage lattice filter if x(n) is the input?
