Abstract
An apparatus for converting an analog signal into a digital signal includes: two identical analog-to-digital-converters converting the analog signal into first and second digital time domain signals; first and second transformation units transforming the first and second digital time domain signals into first and second digital frequency domain signals; a frequency compensation unit modifying the second frequency signal to reduce a difference between wanted signal components of the second and first frequency values caused by a difference between frequency responses of the analog-to-digital converters; a comparison unit determining for a same frequency bin corresponding first and second energy values associated to corresponding frequency values of the first and second digital frequency domain signal, and determining a minimum energy value thereof; and a selection unit selecting for a same frequency bin of the digital frequency domain signal the digital frequency domain signal associated to the minimum energy value.
