Abstract: Example channel circuits, data storage devices, and methods for asynchronous sampling from an oversampled analog-to-digital converter are described. The channel circuit may include an analog-to-digital converter configured to generate an oversampled digital signal from an analog data signal using a sample rate that is an integer multiple of the baud rate of the channel circuit. A digital sample interpolator may then interpolate interpolated digital signal values from multiple signal values of the oversampled digital signal and select values at baud rate to generate a baud rate digital signal. The baud rate digital signal may be used by an iterative detector in a timing loop and, once a target timing is achieved, for the iterative detector to detect data bits from the interpolated digital signal.

Abstract: For holding together flexible materials, such as roll-up display screens, edge-to-edge, very thin and narrow flexible magnetic strip (3) is co-moulded edge-to-edge with non-magnetic flexible strip (4), one face (7 or 5) of the combined strip (1 or 2) being suitable for the application of an adhesive, e.g. in the form of double-adhesive tape (8, 9), and the other face (5 or 7) being provided with indicator means for the polarity of the magnetic portions (3) e.g. different colouring pigments in the non-magnetic portions (4) of co-acting combined strips, or impressions such as a single continuous groove (6) for N-polarity and a pair of grooves (10) for S-polarity.
