Abstract
A digital interpolating system transmits a digital output value that is within a linear range defined by a minimum value and a maximum value input into the system. Another input value, a control value, indicates which value within the linear range should be output by the system as an interpolated output value. The system utilizes a simple hardware design to efficiently implement an approximation of an equation of a line defined by the minimum and maximum values input into the system. The hardware design includes a plurality of switching devices, such as multiplexers or switches, and a plurality of adders to implement the approximation of the equation. By approximating the equation, the system is capable of providing the minimum and the maximum value input into the system as the interpolated output value when the control value is at a minimum and a maximum, respectively.
