Method and device for detecting signals

A device for detecting at least one first signal for a computer, comprising:

• a converter device for converting the at least first signal to a second signal;
• a reference device to which a first reference signal is applied and for converting the first reference signal to a second reference signal;
• a first switching element for switching the second reference signal to the converter device, the converter device converting the second reference signal to a third reference signal;
• a matching arrangement for receiving the second reference signal and matching the second reference signal to a fourth reference signal;
• at least a second switching element for switching the fourth reference signal to the converter device, the converter device converting the fourth reference signal to a fifth reference signal;
• and
• a comparator device for forming a correcting quantity from the third reference signal and the fifth reference signal, wherein:
• the at least first signal is detected as a function of the correcting quantity.

A storage medium for storing a computer program that when executed causes a computer to perform the steps of:

• converting at least one first signal to a second signal;
• applying a first reference signal to a reference device that converts the first reference signal to a second reference signal;
• switching the second reference signal to a converter device that converts the second reference signal to a third reference signal;
• switching the second reference signal to a matching arrangement that matches the second reference signal to a fourth reference signal;
• switching the fourth reference signal to the converter device, the converter device converting the fourth reference signal to a fifth reference signal;
• determining a correcting quantity from a comparison of the third reference signal and the fifth reference signal in the computer;
• and
• detecting the at least first signal as a function of the correcting quantity.
