A method for bioelectric physiological signal acquisition and processing comprising:- a first signal processing operation comprising:/a/ acquiring a first analog signal,/b/ converting the first analog signal in a first digital signal with a first bit depth,/c/ transferring the first digital signal with the first bit depth to a microprocessor- upon reception of a signal to switch from a first operating mode to a second operating mode, a second signal processing operation comprising:/e/ acquiring a second analog signal,/f/ converting the second analog signal in a second digital signal with a first bit depth,/g/ converting the second digital signal with the first bit depth to a converted second digital signal with a second bit depth,/h/ transferring the converted second digital signal to the microprocessor, and/i/ processing the transferred signal on the microprocessor.
