Method for determining at least one wavelet coefficient Ws of a wavelet transform of a signal in which the mother wavelet of the transform has a support subdivided into J\u22671 intervals bound by extremity points, and is defined by a polynomial of a maximum level N\u22671 on each interval. The sampled data values output from the receiver are used to evaluate the integrated circuit’s jitter tolerance. For example, content that includes a form, a hyperlink, a scripted request or other control for initiating a follow-on request to the server is modified to include tokens.
