In this article on the basis of analog-digital systems theory the procedure of synthesis Δ-ADC with multilevel DAC with user of pulse-width modulator is proposed. Jhese Δ-modulators have the high linearity of conversion and the low level of fluctuation noise. The results of imitation simulation are given.
