Abstract: A method for multichannel multifrequency analysis of an object, applying a set of excitation signals to the object and sampling the response signal from the object, using uniform and non-uniform undersampling. Non-uniform sampling of the response signal is performed, i.e., the sampling is performed for two or more different frequencies in one observation time slot. Also, uniform sampling of the response signal is performed, i.e., the sampling of a signal, corresponding to one frequency, is performed for two or more channels within one observation time slot and then sampling the same signal for another frequency for two or more channels within the next observation time slot.

Abstract: A method for synchronizing a RFID receiver, comprising receiving an input signal from a RFID tag, said input signal comprising a preamble section, creating a first reference waveform, comprising at least a fraction of said preamble section, calculating a first correlation value by correlating said input signal and said first reference waveform, creating a second reference signal so that there is virtually zero correlation between said first reference waveform and said second reference waveform, and using said first correlation value and said second correlation value for adjusting synchronization timebase, wherein the sign and the size of said second correlation value indicates the size and the sign of phase inaccuracy of the synchronization timebase.
