| Abstract: | A new technology applying for voltage signal range switch of phase measurement are provided and it improved the precision of phase measurement. The function of monostable multivibrator is realized, and innovated by CPLD chip, which is applied in voltage signal range switch. It provided simulate graph and result. A majority of logic control circuit was integrated in a CPLD chip, This method have advantages of little bulk, responding fast, and working trustness, and attained the expected result. |
