Lissajous figures are defined as “the displacement patterns traced by the electron beam acted upon by two mutually perpendicular sinusoidal signals”

Consider two sinusoidal waves of equal time period and a phase difference acting perpendicular to each other. These are given by

X = a sin (ωt +ϕ ) --------------------------(1) …
