Claim:
1. Method for multichannel multifrequency analysis of an object, comprising: generating a set of excitation signals, said set comprising at least one component with a predetermined first frequency and applying said set of excitation signals to the object through an excitation electrode; generating a set of phase related sampling instances, corresponding to said set of excitation signals; receiving a response signal from the object through at least one response electrode; and sampling said response signal with said set of phase related sampling instances, during a predetermined observation slot, wherein length of said observation slot is determined by said first frequency so that the observation slot comprises an integer number of periods of the signal with first frequency, wherein the samples as the results of said sampling of said response signal are quantized and digitized into a digital code using analog-to-digital conversion, wherein said digitizing comprising:
