Periodic and Non-periodic Signals A continuous time signal is said to be periodic with period Tp for which the signal is advanced in time and remains unchanged. The signal x(t) must satisfy the following condition to be periodic in nature. x(t) = x(t + Tp) for -∞ to ∞ ..........(1) The examples of periodic signals are sine and cosine signals having period (2π/ω0). If a continuous time signal x(t) does not satisfy Eq. (1), the signal is termed as non-periodic or aperiodic signal | |
