Abstract: A receiver circuit is disclosed. The receiver circuit includes a multi-PAM input circuit to receive a multi-PAM input symbol. The input symbol exhibits one of multiple threshold levels during a sampling period. The threshold levels correspond to a set of M-bit two's-complement values within a defined set of threshold values. An adaptive filtering circuit includes a first transcoder to transcode the set of M-bit two's-complement values to a set of N-bit values, where N<M. An adaptive filter operates to filter the set of N-bit values to generate a filtered set of data values. A second transcoder transforms the filtered set of data values to a second set of data values that corresponds to a set of filtered M-bit two's-complement values.

Abstract: An apparatus for weighing full yarn packages which are supported on a transport unit which moves along a trackway in the textile plant. The weighing apparatus includes a weighing station which is positioned at a fixed location along the path of travel of the transport unit, and the weighing station temporarily supports the weight of each package on the transport unit and so as to permit the weight of each package to be sensed.
