Virtual analog to digital converter

摘要

The disclosure relates to analog to digital converters, in particular to logical circuit blocks, a system and a method, which provide functionality of an additional analog to digital converter. In accordance with an aspect of the disclosure, there is provided a logical circuit block, which is configured to be connected to a plurality of ADCs each including a plurality of input pins connected to a plurality of analog input channels. The logical circuit block is further configured to cause one ADC of the plurality of ADCs to perform an ADC conversion of an analog input signal received via a particular analog input channel of the plurality of analog input channels to which an input pin of the one ADC is connected.
