Lisbon , Portugal MEASUREMENT IN A POINT VERSUS MEASUREMENT OVER AN INTERVAL

− The paper reviews and discusses two strategies of digital measurements: measurement in a point and measurement over an interval. The first strategy, widely employed, has represented the backbone in measurement evolution and has become a standard method. For high accuracy measurements, it presents demanding requirements on technology regarding processing of measured signals. The second strategy, recently developed, carries clear advantages in three challenging areas of measurement theory and practice: measurement at high frequencies, measurement of noisy signals and measurements that require high linearity and high accuracy. These three advantages can be combined, as can be seen in the reviewed literature. This paper highlights the most important characteristics of the two measurement strategies.
