Title: Pulse train generator for electric power measurement - has pulse train frequency which is proportional to the product of two analogue electric quantities
IPC: G01R21/133
Filed: 1975-05-02
Abstract: An analogue electric quantity derived from one of the test quantities to be multiplied, is applied to a current-into-frequency convertor comprising an integrator a monostable flip-flop and a reference voltage source. The reference d.c. quantity is superposed on the analogue-electric quantity during a time interval determined by the flip-flop, so that it is in opposition and causes discharge of the integrator capacitor. The flip-flop switching time is controlled by a test quantity derived from the second analogue electric quantity, so that it is inversely proportional to it. The integrator capacitor is therefore charged and discharged in proportion to the product of both analogue electric quantities.
