A signal processing device for providing first and second analog signals includes first and second clocked digital signal path circuits and a transit time difference measuring device. The first clocked digital signal path circuit is configured to yield first digital data for providing a first analog signal. The second clocked digital signal path circuit is configured to yield second digital data for providing the second analog signal. The transit time difference measuring device is configured to yield a transit time difference measuring signal describing a difference between a signal transit time along a first measuring path and a signal transit time along a second measuring path, with the first measuring path including a first clock supply allocated to the first clocked digital signal path circuit, and with the second measuring path including a second clock supply allocated to the second clocked digital signal path circuit.
