Abstract :
The steady-state behavior of the adaptive line enhancer is modeled by the sum of two filters, the Wiener weight filter and a weight misadjustment filter. The effects of randomly time-varying coefficients in the weight misadjustment filter are modeled so as to display line broadening of single frequency ALE inputs.
