Abstract:
1. A device for effectuating a digital estimate of a periodic electric signal, said device comprising: a linear DAC having an output signal; comparing means for comparing said output signal of the linear DAC with said periodic electric signal and producing an output signal based on the comparing; and a logic circuitry having in input the output signal of the comparing means and a pulse clock signal, said logic circuitry providing a first digital signal in input to the linear DAC and a second digital signal representative of the estimate of the periodic electric signal, wherein said first digital signal is formed by a number P of bits, where P is an integer number, and the second digital signal is formed by a number N of bits, where N is an integer number, the number N being higher than the number P, the second digital signal being formed by P more significant bits and N-P less significant bits.
