That is, it performs a constant number of operations for each input symbol.

The device reads a sequence of symbols, transitioning from state to state for each input symbol.

Conversely, in a non-systematic code the output does not contain the input symbols.

However a higher degree of diffusion is achieved because each output symbol depends on 3 input symbols instead of two.

In automata theory, a transition that involves no shifting of an input symbol.

The transitions without consuming an input symbol are called ε-transitions or λ-transitions.

For each input symbol, it transitions to a new state until all input symbols have been consumed.

On the consumption of the last input symbol, if one of these states is a final state, the machine accepts the string.

The only checking of input symbols occurs when the symbol is shifted in.

Thus, for every 24 input symbols there will be 32 output symbols giving .
