Title: Hermannus Schat: Innovator in Television Technology
Introduction
Hermannus Schat is a notable inventor based in Freiburg, Germany. He has made significant contributions to the field of television technology, holding a total of 7 patents. His work has focused on improving the quality and efficiency of television signal processing.
Latest Patents
One of Schat's latest patents involves the frequency conversion of an RF signal transmitted for color television. This innovative method utilizes a 'third method' for frequency reversal, transforming the frequencies of the picture carrier, chrominance subcarrier, and sound carrier into the baseband. This transformation ensures that the frequencies of the transformed picture carrier and chrominance subcarrier coincide, effectively eliminating annoying moire patterns on the screen. By applying a frequency offset, Schat's design shifts spurious signals into a frequency range that is less perceptible to viewers.
Another significant patent by Schat is a television sound receiving circuit designed for at least one sound channel. This circuit converts the transmitted television signal into a composite signal at the baseband using a single-sideband demodulator circuit. It separates the first and second sound channels, producing clear sound signals through subsequent frequency demodulation. The design also includes interfaces for digitization, allowing for the combination of picture and sound signals into a single data stream.
Career Highlights
Throughout his career, Hermannus Schat has worked with prominent companies such as Itt Industries, Inc. and Deutsche Itt Industries GmbH. His experience in these organizations has contributed to his expertise in television technology and signal processing.
