System and method for processing a signal received from a microelectromechanical system.

摘要

The system has a sampling unit (301) for sampling received signal at a sampling rate. A frequency shifting unit (302) shifts the frequency of the sampled signal by multiplication of the signal sampled by an exponential function of the complexes. A low-pass filtering unit (303) filters the frequency shifted signal. Another sampling unit (304) performs sub-sampling of the filtered signal. The frequency shifting unit is adapted to multiply the sampled signal by an exponential function. An independent claim is also included for a method for processing a signal received from a microelectromechanical system.
