An apparatus includes a series connection of at least a first impedance and a second impedance, the first impedance having a first terminal and a second terminal and the second impedance having a first terminal and a second terminal. The second terminal of the first impedance is connected to the first terminal of the second impedance forming a first node. The apparatus further includes a signal generator to apply a first amplitude modulated signal to the first terminal of the first impedance and a second amplitude modulated signal to the second terminal of the second impedance; and further includes an evaluation device configured to receive a first measurement signal from the first node and to determine information on the at least one physical parameter depending on the first measurement signal.
