For a continuous time signal x(t) to be periodic with a period T, then x(t+mT) should be equal to:
A. x(-t)
B. x(mT)
C. x(mt)
D. x(t)
Answer:A
For a continuous time signal x(t) to be periodic with a period T, then x(t+mT) should be equal to:
A. x(-t) B. x(mT) C. x(mt) D. x(t)
Explanation: If a signal x(t) is said to be periodic with period T, then x(t+mT)=x(t) for all t and any integer m.
