Abstract :
In quasi-integer-period sampling, the error of the average value derived from the sampling data is different for different processing methods. However, proper selection of the starting sampling point can reduce this error significantly. The problem is studied more thoroughly in the frequency domain, and it is shown to what extent this error can be diminished and what the residual error is.<>
