An electronic signal mixer is provided for combining first and second signals by additively (or differentially) combining the first and second signals to provide a first output signal. The first and second signals are further combined in a multiplier circuit to provide an output signal which is a differential (or additive) combination of the first and second signals multiplied by a coefficient determined by a control voltage applied to the multiplier. The first combined signal and the product output of the multiplier are further combined to provide a resultant signal comprised of any proportionality of the first and second signals in accordance with the value of the control voltage.
