[en] Designed is an 8-input analog-digital converter which provides for input of the data from the transducers into the computer, thereby improving accuracy of the target parameter monitoring at the p-p scattering. The converter is made on the basis of a functional generator with linear modulation of the output frequency. The functional diagram of the converter is described and its brief characteristics are considered. The converter employs basically the microcircuits and incorporates only one ''voltage-frequency'' converter for eight inputs. The analog-digital converter features low integral non-linearity of about 0.7% and high temperature stability of the conversion characteristic of about 0.03%
