[DEMUX4.BBX 2KB]
This simple network is designed to be imported into a larger network. It functions as a 4-bit demultiplexer. The binary pattern in the four input neurons selects the appropriate output neuron which then becomes active iff the input X is active. The opposite of this network is MUX4.
To create a 3-bit demultiplexer, delete input neuron 8 and output neurons 8-15.
