Abstract
An alternating current watt transducer including an integrated circuit analog multiplier, providing four quadrant multiplication, to the input terminals of which are applied alternating current signals proportional to the voltage and current determinative of the watts to be measured. The integrated circuit analog multiplier provides an alternating current output signal which being proportional to the product of the in-phase components of the input signals, is proportional to the watts being measured. The alternating current signal which is proportional to watts is transformed to a constant-current direct current output.
