Description

рел ции между этими сигналами шума, который и служит дл .определени  скорости движени  магнитной ленты.relativities between these signals of noise, which serves to determine the speed of movement of the magnetic tape.

Предлагаемый способ позвол ет не только уменьшить погрешность измерени , но и упростить процесс измерени .The proposed method allows not only to reduce the measurement error, but also to simplify the measurement process.
