Abstract

According to an aspect, there is provided a merging unit (101) comprising one or more input interfaces (105) for receiving a plurality of input signals characterizing one or more voltages and/or one or more currents measured by a plurality of measurement devices (101), digital processing means (103) and one or more output interfaces (106) for outputting an output signal. The digital processing means are configured to high-pass filter, using one or more digital filters, at least one of the plurality of input signals for lowering a time constant associated with said at least one of the one or more input signals to match a target time constant or for raising a high-pass cut-off frequency associated with said at least one of the one or more input signals to match a target high-pass cut-off frequency and to merge, following the high-pass filtering, the plurality of input signals into the output signal having a pre-defined output format.
