p-normalized digital two-pairs

A digital two-pair constrained by any unity magnitude all-pass transfer function and exhibiting unity L
p
-scaling norms of the transfer functions at all pertinent nodes is defined to be a p-normalized digital two-pair. Several such first-order two-pairs are developed, and the advantage of using these two-pairs in the realization of an arbitrary infinite-duration impulse-response (IIR) digital transfer function is pointed out.
