Abstract

This paper explains the effects of nonideal circuit elements upon the performance of analog and sampled data adaptive filters. It is shown that the effects in case of analog implementations differ significantly from that encountered in ideal case. Moreover, it is shown that effects of nonzero mean errors, such as offset voltages and nonlinearities of the input multipliers contribute n excess mean square error which is inversely convergence of the updating algorithm. To overcome most of these errors, solutions are presented and discussed.
