Abstract
A device for effectuating a digital estimate of a periodic electric signal is described. The device comprising a linear DAC having an output signal, a comparator that compares the output signal of the linear DAC with the periodic electric signal, and logic circuitry having in input the output signal of the comparator and a pulse clock signal. The logic circuitry provides a first digital signal in input to the linear DAC and a second digital signal representative of the estimate of the periodic electric signal.
