An electromagnetic pressure regulation valve including an electromagnetic actuator that positions a piston that is received axially movable in a controller housing, wherein the piston is configured to open and/or close connections of the pressure control valve for flow through, wherein the piston includes a pin at a face surface that is oriented away from the electromagnetic actuator, wherein a relative movement is facilitated between the pin and the piston, wherein a pin face that is oriented away from the piston in the controller housing is arranged opposite to a stop, wherein the pressure control valve includes a hydraulic end position damping for damping a movement of the pin in a direction towards the stop.

The invention relates to a hydraulic transmission valve with a magnetizable housing which is integrally configured in one piece with a pole core cone. The transmission valve according to the invention facilitates comfortably coupling in particular startup clutches, shifting clutches or synchronization clutches in a friction locking manner. Still using a transmission valve of this type is facilitated for fewer to no transmission oil changes. Furthermore a transmission valve of this type can also be used in countries with inferior transmission oil quality. The housing includes a connection. The connection defines an anchor stroke and a concentric arrangement between the pole core cone and a pole tube. Thus, the pole tube is fixated the magnetizable pole flange. An anchor that is exclusively supported in the pole tube is magnetically separated from the pole tube through a separation layer with a thickness of 0.01 mm to 0.06 mm.

A receiver for an optical signal is described. The receiver comprises a decision feedback equalizer (DFE), wherein a distorted input signal (DIS) being derived from the optical signal, as well as a first threshold signal (Th) and/or a first coefficient (Coeff) are provided to the decision feedback equalizer (DFE), and wherein an error signal (ES) is provided by the decision feedback equalizer (DFE). The receiver comprises a control unit (CU), wherein the error signal (ES) is provided to the control unit (CU), and wherein the first threshold signal (Th) and/or the first coefficient (Coeff) are adapted by the control unit (CU). The receiver comprises an eye monitor (EM) for optimizing the adapted first threshold signal (Th) and/or the adapted first coefficient (Coeff), wherein the distorted input signal (DIS) is provided to the eye monitor (EM).

The pipeline analog-to-digital converter has a number of subsequent comparator stages () where the thresholds of the comparator stages are adjusted in accordance with the digital conversion results from previous stages () so as to implement a non-linear conversion scale. In particular, the pipeline analog-to-digital converter consists of a number of comparator stages (), which operate in accordance with a common clock signal. The comparator stages are connected in series in such a way that a residue signal from a previous stage is used as input signal of a subsequent stage for comparison during the next clock period of the clock signal. At least some of said comparator stages have, according to the invention, a threshold generator () for adjusting the threshold value of the respective comparator () in accordance with comparison results of previous comparator stages ().
