| Abstract(in English) | This paper proposes a novel sinusoidal parameter analysis method using vector-based operation and pseud-IQ signals translation by delay devices. In general, caluclating sinusoidal parameters by limited data samples is difficult. Presented method is a practical inverse-problem solution for sinusoidal parameter calculation．Presented method consists of 1) instantaneous frequency measurement unit utilizing phase difference caused by delay devices, 2) quadrature signals generation by frequency dependent linear composition, 3) vector products operation for phasor angle. Presented method basically requires only 5 samples for the sinusoidal parameter calculation. This paper explains principle and the implementations and shows evaluation of preciseness. An F0 estimation application is also illustrated. |
