| Abstract: | In this paper,the quasi-synchronous sampling algorithm is extended to more general cases, where the sampling frequency is lower or much lower than Nyquist frequency,and there exists an undesirable asynchronous deviation.Using this new method,some of the characteristic quantities, such as active power,of periodic signals ranging from power frequency to supersonic frequency could be evaluated more accurately. |
