Block implementation of recursive digital filters--New structures and properties
Sanjit K. Mitra, Ramachandran Gnanasekaran · IEEE Transactions on Circuits and Systems · 1978
Several new structures for the block implementation of HilR digital filters are proposed. The relation between the pole locations of the block structure to that of the original scalar transfer function is derived. A method to obtain the scalar transfer function from a given block structure is described.
