摘要：

The paper considers the errors arising in the direct estimation of the frequency response of linear systems, when only finite lengths of input and output records are available. Open-loop and closed-loop systems are considered. It is shown that the resultant estimates are distributed about a biased mean value. Simulation studies support the theoretical predictions.
