Lattice Dynamics Kit
It consists of an Audio oscillator with amplitude control and facility to vary the frequency from 0.9 KHz to 90 KHz. It has built in power supply and output stage to match the impedance of simulated lattice. Another part of Lattice Dynamic Kit consists of transmission line, which simulates one dimensional mono-atomic and diatomic lattices. The only additional equipment needed is a General purpose C.R.O
