Abstract
There is disclosed a method and apparatus for measuring a signal using a measurement system. The signal has a frequency component that is to be detected by the measurement. The frequency component has a varying phase. The signal has at least one interruption thereto. The method includes: processing the signal with the measurement system to detect the frequency component in the signal and stalling the measurement system before the start of the interruption. The stall period is calculated such that the processing of the signal is resumed: i) after the end of the interruption, and ii) where there is substantially no discontinuity between the phase of the frequency component in the signal at the end of the stall and in the phase of the frequency component in the signal at the beginning of the stall.
