Abstract

A novel method for full characterizing nonlinear distortion of all‐optical sampling is proposed based on polynomial transfer function.The method only requires fitting transfer curve with a polynomial function and enables a uniform expression of nonlinear distortion in terms of polynomial coefficients and input parameters. Simulation and experiment are designed and performed to check the accuracy. The results with our method are in good agreement with the measurement. Our method avoids both Fourier expansion and spectrum measurement, which is suitable for fast evaluating and optimizing distortion of all‐optical sampling. Β© 2010 Wiley Periodicals, Inc.

This paper gives a characterization of all transfer functions that may be realized via regular static-state feedback for a SISO nonlinear control system. It is shown that the question whether there exists a feedback realizable transfer function with a given number of zeros may be reduced to a well-k

A method is presented for investigating the errors incurred when the low-order parameters of an all pole system are measured by the Hermite modulating function technique. The correlation form of the basic linear system equations is used. It has been found that measurement errors are a function of th
