摘要：
The use of Fourier analysis as a step in building a model of a linear dynamic system involves end effects which introduce bias and variance in estimates. The source of these errors is considered, and their detailed form is estimated. This leads to a significant improvement in the accuracy of the final model. Simulation results are included.
