Abstract
An apparatus for measuring the impedance of body tissue has a signal source connected to the tissue to be measured which supplies an electrical signal to the tissue, a unit for acquiring an impedance signal from the body tissue dependent on the electrical signal, and an evaluation stage for the impedance signal. The evaluation stage filters out low frequency signal components corresponding to the conductance of the tissue, and has a signal output to which the signal components which were filtered out are supplied.
