Abstract
PURPOSE:To obtain the vector component of the input signal via the digital value by securing generation of the standard sine wave with the digital signal and then giving the n-cycle integration to the product of the standard sine wave and the input signal. CONSTITUTION:The one cycle of the reference signal of the sine wave is divided, and the waveheight value corresponding to each angle is memorized in memory part 4 in the form of the digital value. Then the analog input signal which is the measured signal from terminal 1 plus the digital signal read out of part 4 are supplied to D/A converter 3 to obtain the analog signal proportional to the product of the both. Then this output is supplied to double integration type A/D converter 7 to carry out the integration for one cycle via the integration gate signal sent from preset counter 5. Thus the digital value is delivered through terminal 18 for the preset phase component vector of the input signal. In such way, the vector component can be obtained with a high accuracy and through a simple circuit.
