Given the transfer function below

\[H(z)=-z^{-2 N}+\cdots-z^{-6}+z^{-4}-z^{-2}+1\]

where \(M\) is an odd number:

(a) Show a realization with the minimum number of adders.

(b) For a fixed-point implementation, determine the scaling factors of the filter for the \(L_{2}\) and \(L_{\infty}\) norms.

(c) Discuss the advantages and disadvantages of the given structure with respect to its transposed version.
