Reproducibility and repeatability are measures of closeness with which a given input may be measured over again. The two terms cause confusion. Therefore, a distinction is made between the two terms. Reproducibility is specified in terms of scale readings over a given period of time.
On the other hand, repeatability is defined as the variation of scale reading and is random in nature.
Q. For a transmission-line model that includes only the series impedance Z, sketch phasor diagrams for: (a) Lagging power factor load. (b) Leading power factor load.
Consider the following signals, sketch each one of them and comment on the periodic nature: (a) x(t) = A cos(2πf 0 t + θ), where A, f 0 , and θ are the amplitude, frequency, and
