Jitter is a crucial factor in high speed and high performance ADC testing. This paper proposes an efficient and accurate jitter estimation method based on one frequency measurement. Applying simple mathematical processing to the ADC output in time domain, the RMS of jitter and noise power are obtained. Furthermore, prior information of harmonics does not need to know before the processing. The algorithm...
This note derives a novel alternative state-space formulation of 2D frequency transformation for 2D digital filters by utilizing linear fractional transformation (LFT) techniques. It turns out that the obtained new state-space formulation is much simpler than the existing result. Moreover, all the known 1D and 2D formulations can be unified by the proposed formulation as special cases. Numerical examples...
