The measurement method of sinusoid parameters is presented. The amplitude, frequency and phase of sinusoid can be measured synchronously by recursive predictive error(RPE) algorithm which has the advantages of low memory, easy programmability, online measurement, high measurement precision, etc. The experimental results are also given.
