Model 257 Dual Control Voltage Processor

Consists of two identical sections, each of which permits several applied control voltages to define a single output voltage according to the equation:

V_a * K + V_b * (1 - M) + M * V_c + V_offset = V_out

The algebraic manipulations possible with this module include addition, subtraction, scaling, inversion, and multiplication. Also incorporated is the capability of using one control voltage (M) to transfer control from one applied voltage (V_b) to another (V_c).
