**Keywords:** analog-to-digital converter; linearity error; simulation mod**Abstract:** Analog-to-digital converters (ADC) are the most
commonly used converters at measuring and control devices. The
transfer function of a real ADC is different from the ideal one.
There are additive, multiplicative and nonlinear components of
the error. The number of bits of any ADC is finite, which results
to the appearance of quantization error. Due to the presence of
aperture delay and aperture jitter, there is a variable in time
delay of sampling of the input signal. In case of measuring the
integral parameters of the signal (root mean square value, active
power, reactive power, apparent power, etc.), the evaluation of
the impact of the ADC nonidealities at an analytical form is a
difficult task. This is especially true in the case of nonlinearity
and quantization error. For this reason, it is of interest to
estimate the measurement error by performing simulation
mathematical modeling. The problem under consideration is also
relevant in the educational process for all areas related to
