Abstract: A new class of fixed partial response targets are disclosed for use in a PRML magnetic medium read channel. The preferred embodiment exhibits an equalization response characterized by the polynomial 7+4*D−4*D2−5*D3−2*D4, where D represents the unit delay operator. This read channel target provides improved matching to the inherent magnetic channel over the known canonical class of targets (1−D)(1+D){circumflex over ( )}N, and thereby reduces equalization losses. The improved spectral matching reduces amplification of noise in the channel, thereby reducing bit-error-rates. The new class of targets also exhibits a spectral null at DC, reducing problems for offset cancellation circuitry and making the disk drive less sensitive to thermal asperities. It also exhibits a spectral depression rather than a spectral null at the Nyquist frequency, making quasi-catastrophic error sequences virtually impossible.

Abstract: A pennant construction (10) for a vehicle antennae (100) comprising a pennant member (20) fabricated from a very thin, lightweight, and strong material (21) formed into a generally triangular configuration and having an adhesive strip (24) formed on one side and adjacent one edge of the pennant member (20) for adhesively securing the pennant member (20) both to the antennae (100) and itself.
