Boolean circuits, however, only allow a fixed number of input bits.

The erasure represents complete loss of information about an input bit.

It works as a switch, redirecting input bits to at one moment and to at another.

It is possible therefore to pre-calculate the output bit based upon pre-determined input bits.

That is, a total of 384 input bits are compressed together to 128 output bits.

That is, every output bit depends on every input bit.

It will also have the property that each output bit will depend on every input bit.

In a noisy broadcast model, processors are assigned a local input bit .

If the input bit above the leftmost divisor bit is 0, do nothing.

The new output bit is the next input bit.
