Zusammenfassung:	Circuit for evaluating resolver sensor signals (28) in a vehicle, having a resolver sensor (4), set up to pick up a rotary movement of a rotor (6) in an electrical machine (16), and a processor element (12), wherein the resolver sensor (4) is set up to output at least one sinusoidal or cosinusoidal amplitude-modulated analog signal that is characteristic of the rotary movement of the rotor (6), characterized in that the processor element (12) has a data processing unit (12a), a resolver sensor actuation unit (12b) and a resolver sensor evaluation unit (12c), wherein the analog signal from the resolver sensor (4) is connected directly to the resolver sensor evaluation unit (12c).
