## A method for generating an all-pole stable transfer function to approximate a constant group delay is developed. The mean square error between the actuaI group delay and the spectjiedgroup delay is minimized. Also, the computational complexity is considerably reduced.

An approximation procedure is developed whereby a discrete domain transfer function is obtained which will approximate a constant group delay. This minimizes the mean square error between the actual group delay and the specljied group delay. The method is illustrated by an example.

Error estimates are given for the approximation of stable recorded delay systems in the L 2 and Hยฎ norms, using two recently advocated techniques based on Laguerre series. In addition, some theoretical results on L~(0, oo) approximation are derived.
