Title: The Innovations of Alfred C. Schroeder
Introduction
Alfred C. Schroeder is a notable inventor based in Southampton, PA (US). He has made significant contributions to the field of television technology, particularly in ghost signal cancellation systems. With a total of 3 patents to his name, Schroeder's work has had a lasting impact on video signal processing.
Latest Patents
One of Schroeder's latest patents is a "Sampling arrangement for a television ghost signal cancellation system." This invention includes a gate that receives a ghost-contaminated video signal, allowing for the extraction of a main signal component for training purposes. The gated signal is processed through a differentiator, which produces signals corresponding to both the training signal and ghost components. A clipping limiter then generates a sampling signal that focuses on the training signal, effectively excluding ghost signals. This innovation is crucial for developing a time sequence of samples that can be used in ghost eliminators.
Another significant patent is the "Input-weighted transversal filter TV ghost eliminator." This invention features a transversal filter that processes a detected video signal through multiple stages. It develops weighting function signals that are applied to input taps, which help reduce ghost signal components in the processed video output. This technology enhances the quality of television signals, making it a valuable advancement in the industry.
