sinusoidal signals are
applied to the Χ - and Y-axis is called α
L issajous
figure . This display is commonly
used to compare
the frequency and phase relationships
of two input
signals . The fre q uency
relationship of the two input
signals d etermines the pattern
seen . The pattern will
be
stable only if α common
divisor exists between
t he two frequencies .
