Input-weighted transversal filter TV ghost eliminator

摘要

A television signal ghost eliminator is described, including a transversal filter having an input terminal, an output terminal at which a processed video signal is produced, a plurality of signal processing stages serially coupled between the input and output terminals, and a plurality of input taps coupled to the signal processing stages. A detected video signal is applied to the input terminal of the transversal filter and is transferred through the serially coupled stages. A circuit is responsive to the processed video signal for developing a plurality of weighting function signals which are applied to the input taps. The weighting function signals applied to the taps are combined with the detected video signal as it appears at the tapped stages, resulting in reduction in ghost signal components in the processed video signal which is produced at the output terminal of the transversal filter.
