| Abstract | A rheostat is an adjustable resistor so constructed that its resistance may be changed without opening the circuit in which it may be connected. Conventional rheostats are adjusted mechanically. This thesis presents a method of adjusting resistance electrically by varying the light intensity incident on the surface of a photoconductive cell. A feedback scheme is used to linearize resistance response to an adjustment voltage. Absolute electrical isolation is maintained between the rheostat adjustment and signal channels. Significant design parameters are identified. A practical design is presented, and its performance is described. |
