Abstract :
The problem of estimating the error due to the discrete-time approximation in sampling digital wattmeters is dealt with. The complementary characteristics of two different sampling strategies, based on equally spaced or randomly generated sampling instants, are discussed. A mixed-mode sampling strategy, which can also provide an estimate of the error, is proposed.
