A Ternary Storage Element Using a Conventional Ferrite Core

A new group of time-delay polynomial approximations are obtained by trial and error methods. The results of the trial and error procedure suggest an analytic method for finding the new approximations. The new approximations and their usable bandwidths are tabulated for second-through sixth-order polynomials. Delay vs. frequency graphs of the fourth-and fifth-order polynomials are compared with several previously published approximations.
