Abstract
Recursive adaptive filters which utilize a stochastic gradient search algorithm in order to optimize their coefficients are apt to converge to local minima if the meansquare error surface is not unimodal. Such conditions are known to result since the IIR mean-square error surface is not quadratic. Two-dimensional adaptive filter error surfaces are examined in this paper, and their properties are seen to be very similar to those of 1-D IIR adaptive filter error surfaces.
