Abstract
A receiver or preamplifier for differential signals, in particular electrocardiogram signals, includes n electrodes to provide at least one signal at an acceptable common mode rejection ratio, even if the subject to which the electrodes are applied has a different ground potential than the assigned monitor. This is achieved by two current sources which are controlled by a sum signal representing a sum of the electrode signals, said current sources injecting a corresponding current into the electrodes.
