Abstract
A device having a variable output electrical characteristic includes first and second output terminals and a number of switching circuits, each switching circuit having two states. One of the states produces a first electrical effect (such as an increased resistance) between the first and second output terminals, and the other state produces a second electrical effect (such as no change in resistance) between the first and second output terminals. A processor generates control signals that are applied to the switching circuits to place the switching circuits into a desired state such that the variable output characteristic between the first and second terminals is set to a desired value, which may be input from a user.
