In the one dimensional Toda lattice it is possible to create a delaythat can be controlled. The lattice has been used to create logic gates forcomputation, but the delay mechanism so far has not been incorporated.With this controllable delay a XOR and OR gate can be designed thatcan be used for computing. The delay for a travelling soliton is createdby a harmonic lattice between two Toda lattices. The duration canbe controlled by changing the time when a second soliton is scatteredagainst the harmonic lattice after the first soliton. This work shows thatif the duration is to short, there will not be any transmission, only whenthe duration between the two scatterings are long enough a transmissionwill become visible and this transmission depends on the energy of thesolitons. This work shows how this controllable delay can be applied inthe construction of two logic gates.
