Abstract: An electronically programmable function generator with two dimensional programmability is provided which has an output, a current, which is a piecewise linear function ("transfer curve") of its input, a voltage. The transfer curve consists of contiguous straight line segments and the breakpoints between the line segments are electronically non-interactive and independently programmable. The generator in its preferred embodiment linearizes the response of a non-linear amplifier or can be utilized wherever an empirical non-linear function is needed in an analog system.
