Abstract

A method for converting an analog input signal (α) into a sequence of digital output values (θn) uses the formation of a first differential value (ϵ) between the current output value and the analog input signal (α). The method also provides for a check to determine whether the amount of the first differential value (ϵ) exceeds a predetermined amount (S). Should the amount of the first differential value (ϵ) exceed the predetermined amount, the method provides that the digital output value (θn) is re-adjusted using a certain adjustment value. Should the amount of the first differential value (ϵ) not exceed the predetermined amount, the method provides that a second differential value (δ) between the first difference (ϵ) and an integral value (Σ) consisting of the sum of first differential values (ϵ) occurring since the checking stage showed throughout that the amount of the first differential value (ϵ) does not exceed the predetermined amount is formed; and that the second differential value (δ) is compared with a predetermined threshold value and the digital output value (qn) is incremented or decremented according to the result of this comparison.
