	The XIR element stands for '''Resistor array''' and is actually more of a ''electrical low level'' building block for an analog computer. It has a number of inputs with different weights which are translated to currents at the [[summing junction]]. This way, you can extend [[Integrator]]s, [[Summer]]s or [[Inverter]]s with more inputs. To do so, just connect the summing junctions of the respective elements.
