Title: The Innovations of Friedrich Gierlinger
Introduction
Friedrich Gierlinger is a notable inventor based in Markt Indersdorf, Germany. He is recognized for his contributions to the field of signal processing, particularly in the area of chrominance signal modulation. His innovative approach has led to advancements in how color information is transmitted and processed.
Latest Patents
Gierlinger holds a patent for a method of producing a modulated chrominance signal with suppressed carrier. This method involves applying a square-wave carrier signal and a color information signal in the form of a sequence of digitally encoded amplitude values to a modulator arrangement. The clock frequency for the amplitude values is an integral multiple of the color carrier frequency and is phase-locked to it. Each bit of the amplitude values is inverted during one half cycle of the carrier and remains unchanged in the subsequent half cycle. Additionally, specific values are added to ensure total carrier suppression for the desired input signal level. The resulting modulated analog chrominance signal is available after digital-to-analog conversion.
Career Highlights
Gierlinger has made significant strides in his career, particularly while working at U.S. Philips Corporation. His work has been instrumental in enhancing the quality and efficiency of color signal processing technologies.
Collaborations
