Patent ID: 7480355

Claim:
Within a measurement instrument, a method of removing data dependent jitter from a symbolic representation of a digital signal, the method comprising the steps of: (a) digitizing a digital signal of interest to create a sequence of sampled values there being a plurality of sampled values for each bit in the digital signal of interest; (b) processing the sampled values of Step (a) to form an Acquisition Record that is a symbolic representation of the time variant behavior of the digital signal of interest; (c) identifying, for each bit of the digital signal of interest whose time variant behavior is represented in the Acquisition Record of Step (b), a respectively associated amount of data dependent jitter that is known to be associated with each bit of the digital signal of interest; (d) modifying the Acquisition Record of Step (b) to remove from the symbolic representation of each bit therein the respectively associated amount of data dependent jitter identified in Step (c) the respectively associated amount of data dependent jitter identified in Step (c) for a particular bit being removed by modifying more than one of the sampled values in the Acquisition Record; and (e) supplying to a using environment the modified Acquisition Record of Step (d).
