Which consequence results when errors accumulate in recursive noise cancellation?

💡 Explanation

Recursive noise cancellation depends on accurately estimating and subtracting noise; error accumulation causes the estimate to diverge spuriously, creating a comb filtering effect because regular frequency nulls appear. Therefore the signal is distorted, rather than having reduced noise or improved timing.
