发明名称 Anti-reflection circuit for video and teletext signals with subdivision of the global filter in a plurality of filters with a reduced number of coefficients.
摘要 <p>The present invention relates to an anti-reflection circuit for video and/or teletext signals, comprising one or more numeric filters and a processor; the main characteristic of the invention consists in the fact that the circuit comprises a filtering section, composed of at least one numeric filter, and an elaboration section, entrusted to said processor, and that the elaboration section provides for reducing the number of coefficients from a number M to a number N lower than M, carrying out an elaboration, so as that the filtering section, in its assembly, implements an adaptive filter of a wide support but being of a reduced number of coefficients. &lt;IMAGE&gt;</p>
