ABSTRACT:
A first matrix relationship is defined by a plurality of switches operative in first and second states in accordance with the logic levels of binary signals introduced to the switches. The switches in the matrix relationship receive binary signals of relatively high binary significance. An activating line is connected to the matrix relationship to activate storage members, such as capacitors, connected to the matrix relationship. The number of storage members energized by the activating line at each instant is related to the value coded by the logic levels of the binary signals introduced to the matrix relationship. For increasing binary values, the storage members previously energized in the plurality by the activating line continue to be energized and additional storage members in the plurality are energized. An interpolating line is also provided in the first matrix relationship. The interpolating line receives a voltage related to the binary value coded by the logic levels of the binary signals of relatively low binary significance. This voltage may be produced by a second matrix relationship of conventional construction. This voltage is introduced through the interpolating line to a particular one of the storage members in the plurality, this storage member constituting the next to be connected to the activating line for increasing binary values. An output signal is produced corresponding to the cumulative value of the energy stored in the storage members in the plurality and in the particular storage member. The output signal may be produced by an integrator amplifier connected to the storage members in the plurality.
