  1. Система для аналого-цифрового преобразования включает в себя средства приема входного аналогового сигнала, средства для введения подмешиваемого псевдослучайного колебательного сигнала и аналогового сигнала в цифровой преобразователь с целью преобразования объединенного входного сигнала и колебательного сигнала в цифровую величину. Согласно изобретению колебательные средства выдают колебательный сигнал с формой, включающей в себя первый периодический колебательный сигнал с наложенным и формирующим вторым сигналом, содержащим по крайней мере одну компоненту, которая изменяет первый периодический колебательный сигнал в пределах по крайней мере одного интервала квантования аналого-цифрового преобразователя. 1ил.
