Title: Innovations by Jeffrey Marc Kletsky
Introduction
Jeffrey Marc Kletsky is a notable inventor based in San Francisco, CA, with a significant contribution to the field of digital communications. He holds five patents, showcasing his expertise and innovative spirit in developing advanced technologies.
Latest Patents
One of Kletsky's latest patents is a non-invasive digital cable test system. This invention provides a method and apparatus for non-invasive testing of digital communications systems. Amplitude measurements are made for multiple frequencies of a multi-frequency communication system, which are then converted to the time domain. An adaptive filter output is matched to the time domain representation to characterize the channel. This technique allows for precise location of impedance mismatches. An error signal representing the difference between a transmitted signal and a received signal is estimated and analyzed. The error signal is separated into components corresponding to contributions from wide band noise, residual phase modulation, and residual amplitude modulation. Identification and removal of narrow-band interferers may occur prior to this separation. Bit error rate and system margin computations utilize a Monte Carlo simulation of various error sources, providing a well-refined estimate of bit error rate and system margin.
