Abstract

An apparatus generates a biomedical data signal representing a multichannel biomedical signal comprising biomedical channel signals for measured differential voltages between two measurement electrodes. A determination circuit (103) derives a reference signal from the biomedical channel signals, e.g. as an average signal of the channel signals. A compensation circuit (105) generates compensated biomedical channel signals by compensating the biomedical channels signals for the first reference signal, e.g. by subtracting the reference signal. A data encoder (107) generates encoded compressed data for the compensated biomedical channel signals and a data signal generator (109) generates the biomedical data signal to comprise the compressed encoded data. An apparatus may receive the biomedical data signal and perform the reverse operation of first determining compensated channel signals and then compensating these by the reference signal to generate the biomedical data signal.
