Abstract
A method and an apparatus for compressing and displaying digital data, in particular beat-to-beat heart rate data in fetal monitoring, operates according to the principle of the "maximum absolute differences", i.e., the data discovered in a certain interval are compared with a start value, and the data with the highest absolute difference in relation to said start value is chosen as representative for the data discovered in such interval. This results in an effective data compression, without suppressing higher-frequency signal components--which are very important for certain applications--significantly.
