A signal y(t) is periodic with fundamental period T0, and is the sum of two other signals y(t) = x1(t) + x2(t). Must x1(t) and x2(t) both be periodic?
Solution
The sum of two periodic signals x1,x2 with periods T1,T2 is periodic only if the ratio of T1/T2 is a rational number or ratio of 2 integers.X1,X2 must be periodic.To is the LCM of T1,T2.
