INDUKTIVER STEUERKNÜPPEL UND SIGNALVERARBEITUNGSSCHALTUNG DAFÜR

摘要

In an electronic signal processing circuit for an inductive joystick having a primary induction coil (10) and at least one secondary circuit (the or each secondary circuit e.g. 32 comprising first and second coils 12, 14), the outputs of the secondary coils (12, 14) are connected via respective rectifying means (42, 44) to a combining means (50). The combining means (50) provides a resultant signal (i) according to the difference between the outputs of the first and second coils (12, 14) and representing the deflection of an actuator of the joystick.
