1. An analog-to-digital converter system comprising:
a sampler configured to sample an input signal and provide at least two output signals with a predetermined output sample rate;
an analog-to-digital converter for each one of the output signals and configured to convert the respective output signal into a digital signal with a predetermined converter sample rate, wherein the converter sample rate is higher than the output sample rate; and
a signal processor configured to receive the digital signals and to determine the highest signal value and the lowest signal value for at least two samples of the digital signals in each sampling period of the sampler, and to determine a sample value for a respective sample for each one of the digital signals based on the determined highest signal value and lowest signal value.
