Abstract
A system for simulating the insertion of electric resistance values of either positive or negative quantity into an electric circuit and for cancelling drift errors therefrom.
Claims10
A combination of components for simulating the insertion of selected resistances of either positive or negative values in an electric circuit comprising:
- a. a first amplifier means for providing an output voltage equal to a constant times a current in said circuit,
- b. a multiplier operatively connected to said first amplifier for receiving said output therefrom,
- c. means for providing a selected input of a manipulated value into said multiplier as a second input thereto whereby the output of said multiplier is the product of said selected input, a constant and said current, and
- d. a second amplifier means, operatively connected to said multiplier to receive said output therefrom as a first input and operatively connected to receive an input representative of the input to said first amplifier means as a second input, for providing an output of said combination equal to the product of a constant, said selected input and said current.
