ABSTRACT:
A holding device for a sensor signal comprises a signal input receiving a sensor signal, a signal output and a storage device coupled to the signal input and output. The storage device is designed to store a signal value in a first state and to update it based on the sensor signal in a second state. The storage device stores the signal value for a time period which is greater than a first predetermined time duration, independently of a supply voltage of the storage device. The holding device outputs the signal value present in the storage device. The holding device furthermore comprises a monitoring device, which is effectively coupled to the storage device and determines whether the sensor signal present at the signal input is valid. The monitoring device ensures that the storage device is in the second state only when the monitoring device identifies that the sensor signal is valid.
