| Abstract |
The paper presents a new method of phase measuring based on frequency measurement method. The operation principle and basic formulae for determining phase and frequency are given. Dynamic and static accuracy of the measurement has been discussed. The proposed method applies two measurement Iines, each one having a marker at the beginning of frequency-function measurement cycle. lf the markers occur synchronously then the measurement of frequency and phase is possible. lf they occur asynchronously it is possible to measure the frequency-function of the markers. When the values of the frequency are obtained it is possible to determine the slip value. The operation identification in the terms "synchronous", "asynchronous'', has been done basing on the following criteria: equality of frequency and phase for the measuring range greater than 2pi. The possible applicatlons of the method are the measurements of actual values of: frequency-function, phase, and the quotient of the frequencies. |
