Latest Patents

One of his latest patents is a network measurement method and apparatus. This apparatus measures timing variations, such as jitter or wander in a timing signal of a telecommunications network. A recovered clock signal is sampled and digitized to produce a series of digital clock samples, which are then processed with reference to a local digital reference signal. This process results in the production of digital baseband frequency in-phase (I) and quadrature (Q) components. These components are further processed to produce the digital phase information of the clock signal, allowing for the determination of the required parameters of the network. The step of digitally processing the clock samples can be conveniently implemented using a digital signal down-converter IC, similar to those used in digital radio receiver implementations. For jitter measurement, the local reference signal may be generated by a phase-locked loop, while for wander measurements, an external reference clock is utilized.

Another significant patent is the apparatus and method for generating wander noise. This method involves predefining frequency, amplitude, and phase values for a plurality of tones across various predefined frequency profiles. A digital noise signal with a specific profile can then be generated by summing multiple tones based on these predefined values. The wander noise signal is subsequently generated from the digital noise signal.
