Title: Alfred Schaumberger: Innovator in Signal Processing
Introduction
Alfred Schaumberger is a notable inventor based in Olching, Germany. He has made significant contributions to the field of signal processing, particularly in the development of methods for modulating chrominance signals. With a total of 2 patents, his work has had a lasting impact on television technology.
Latest Patents
Schaumberger's latest patents include a method of producing a modulated chrominance signal with suppressed carrier. This innovative 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, a first and a second value are added to the obtained values, ensuring total carrier suppression for the desired input signal level. The modulated analog chrominance signal is available after digital-to-analog conversion.
Another significant patent is a television test line signal generator. This device comprises a read-only memory that is read under the control of a clocked counting circuit. The memory outputs are connected via a clocked buffer store to a digital-to-analog converter, which is followed by a signal filter. The information in the read-only memory is programmed to address signal distortions that may occur thereafter.
