Researchers at NIST have developed an adaptive functional data analysis method to characterize random timing errors in high-speed sampled signals measured by sampling oscilloscopes. On average, jitter noise blurs a measured signal and reduces its power in the spectral domain. However, given an estimate of the standard deviation of the jitter noise, one can correct the measured power spectrum. This correction dramatically reduces prediction error and is essential for characterizing the impulse response function of high-speed sources and detectors in optical fiber communications systems at high frequencies (up to 50 GHz).
To estimate the standard deviation of ...
