Introduction

Philip J. Nowaczyk is a notable inventor based in Chicago, IL, with a remarkable portfolio of 12 patents. His work primarily focuses on advancements in digital television technology, showcasing his expertise in signal processing and modulation techniques.

Latest Patents

Among his latest patents is the "VSB modulator symbol clock processing to reduce jitter/phase noise and sampling artifacts." This invention involves a translator that demodulates a received digital television signal to produce a digital data stream, a symbol clock, and a byte clock, which are often corrupted by phase noise. The digital data stream is buffered in response to the corrupted byte clock, while the corrupted symbol clock is processed through a frequency/phase locked loop to regenerate a symbol clock with minimal phase noise. This innovation allows for the effective re-broadcasting of digital television signals.

Another significant patent is the "Multiple frequency horizontal scan compensation system." This system detects changes in horizontal scan frequency by monitoring horizontal sync pulses. It employs a frequency-responsive switching system that connects the appropriate reactive components to the horizontal deflection yoke and output transformer based on sync pulse frequency. Additionally, it provides alternative voltages for the scan system operating supply, enhancing the overall performance of horizontal scan systems.
