Title: Innovations by Xiaojun Chen

Introduction

Xiaojun Chen is an accomplished inventor based in Longmont, Colorado. He has made significant contributions to the field of technology, particularly in the area of sample rate tracking. His innovative work has led to the development of a patent that addresses critical aspects of latency in output sample streams.

Latest Patents

Xiaojun Chen holds a patent for "Systems and methods for sample rate tracking." This patent outlines a method that includes computing an actual latency associated with an output sample from an output sample stream. The actual latency is calculated using a phase and a phase increment, which is the conversion rate ratio. Additionally, a measured latency is determined using an internal clock based on the presentation time of the output sample or an input sample from an input sample stream, or both. The measured latency is then compared to the actual latency to generate a latency error. A successive phase increment can be determined based on the latency error by employing a low-pass or adaptive filter to adjust the latency error. This innovative approach enhances the efficiency and accuracy of sample rate tracking.
