Abstract An analogue bipolar passive multiplier, especially for measuring of electrical power, comprising circuits for generating the product ui, wherein u is a DC voltage and i a DC, or the product ui-cos? or ui-sin?, wherein u is an AC voltage and i an AC and ? is the phase angle therebetween, based on the equation (u + i)2 - (u - i)2 = 4ui. The multiplier comprises a voltage divi- der consisting of first and second equal resistors (R1, R1) interconnected at a center point (J) and connected across the voltage input or alternatively the current input (U resp. I) of the multi- plier, and a third resistor (R2) having one end connected to the center point (J) of the voltage divider and being connected across the current input or alternatively the voltage input (I resp. U) of the multiplier. First and second, passive function generators (PFG1) which are constructed for squaring, are connec- ted respectively in parallel with the series connection of the first voltage divider resistor (R1) and the third resis- tor (R2), and with the series connection of the second voltage divider resistor (R1) and the third resistor (R2). The outputs of the function generators (PFG1) are connected to a parallel connection consisting of an output resistor (R4) and a filtering capacitor (C1) and of which the second end is connected to the other end of the third resistor (R2).
