Abstract
In the field of automatic control, there is a need for simple and reliable devices which perform the operations of analog multiplication and division. This paper describes a circuit containing only-magnetic cores and windings, which produces an alternating voltage output directly proportional to the quotient of two d-c input signals. The output is also directly proportional to the alternating voltage used for excitation, which thus may be employed as a multiplier input signal, otherwise a regulated a-c supply is required. Since the circuit contains no semiconductors and is relatively insensitive to changes in the properties of the magnetic cores, it is well-adapted to operation at elevated temperatures.Keywords
