Abstract: A phase detection system (100) comprises an input terminal (101), first and second peak detectors (103, 113), an averaging unit (107), an offset unit (122), and a comparator (126). Input terminal (101) is coupled to the first and to the second peak detectors (103, 113) and provides an input signal to phase detection system (100). Averaging unit (107) is coupled between offset unit (122) and both the first peak detector and the second peak detector (103, 113), and generates an intermediate signal. Offset unit (122) is coupled to input terminal (101) and generates two comparable signals by applying a predetermined offset in signal strength to the input signal or the intermediate signal. The comparator (126) is coupled to the offset unit (122) and generates an output signal by comparing the two comparable signals which is indicative of the phase of the input signal.

Abstract: A sensor (10) has an output coupled to a first comparator input. A control circuit (18) is arranged to switch from an upward tracking mode to a downward relative level detection mode, to a downward tracking mode, to an upward relative level detection mode and back to the upward tracking mode successively. A first and second digital to analog conversion circuit (14a,b) receive a first and second digital control value from the control circuit (18) respectively.

Abstract: What is described is a configuration for determining the position of a body along a movement direction, wherein the body is in the form of a magnetized encoder with two magnetic tracks extending, on one surface of the body, along the movement direction, at least essentially in parallel with one another, wherein, at specified intervals along the movement direction, a first of the magnetic tracks exhibits magnetized sections in which the magnetic north poles are aligned so as to be at least largely coincident in a magnetization direction that is essentially at right-angles to the surface of the body, and wherein, at intervals specified to coincide with the above-mentioned intervals along the movement coordinate, the second of the magnetic tracks exhibits magnetized sections in which the magnetic south poles are aligned so as to be at least largely coincident in the said magnetization direction, and wherein, in each case, a magnetized section of one of the magnetic tracks is located at least largely centrally in
