A proposal of jitter analysis based on a wavelet transform

Abstract

The paper puts forth a proposal for a new jitter measurement method based on a wavelet transform usage. There are many problems associated with the generation jitter free reference clock for measurements. The proposed method does not need a reference clock which is its main advantage over known methods that rely on reference clock usage. Additionally, presented wavelet transform applied to the jitter signals allows for more detailed analysis than offered by other methods. Comparison of classic and wavelet approach is presented. Problems like wavelet function type, order and post processing methods are also indicated.
