DIGITAL SIGNAL TRANSITION SPLITTING METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a digital signal transition splitting method and apparatus that reduce a maximum transition rate of a digital signal. SOLUTION: The digital signal transition splitting method and apparatus reduce a maximum transition rate of a digital signal. The apparatus and method are particularly useful for digital signal processing in communications and for performing digital transition timing testing on a device under test. The apparatus and method split a digital signal into two or more signals, while preserving the relative timing of transitions in the digital signal. A high frequency signal is partitioned by the apparatus and method into a plurality of equivalent lower frequency signals without loss of transition timing information. The apparatus is implemented with readily available components. The maximum transition rate of a digital signal is reduced by a factor of two or more, and is proportional to the number of output signals. A plurality of the apparatuses may be cascaded together into a system to achieve even greater reductions in maximum transition rates.
