Abstract
The relations between the frequency of Lissajous figure and that of input signal are given by theoretical calculation. The formulae of measuring the frequency of an alternating signal through Lissajous figures are revised. The revised formulae are more precise. An experiment is conceived and carried out to prove these formulae.
