Abstract :
The feedback adaptive line enhancer is analyzed, and a closed-form solution is derived for the case where the decorrelation delay is one sample and the filter length is an integer multiple of half cycles of the input sinusoid. The resulting weight vector has a sinusoidal profile but with higher mean amplitude than an equal-order adaptive line enhancer
