Jitter measurement method for multi-level discs based on quadratic interpolation algorithm

摘要

A new jitter measurement method for multi-level discs is presented in this paper. This method, with merits such as high precision, flexible and low cost, combines the traditional pulse counting method and interpolation algorithm. The principle of this method is explained in detail, and its precision is analyzed. The analysis result is shown to be very effective. It has a broad application prospect and practical value in quality evaluation of multi-level discs.
