Periodicity in signals and systems

WebWe introduced two basic periodic signals in Chapter 1, the sinusoidal signal x(t) = cosw 0 t, (3.17) and the periodic complex exponential x(t) =ejw 0 t, (3.18) Both these signals are … WebDiscrete Fourier series representation of a periodic signal Remarks: 1 The frequency 2π N is called the fundamentalfrequencyand is the lowest frequency component in the signal. (We will later show that there is no loss of information in this representation.) 2 We only need N complex exponentials to represent a DT periodic signal with period N.

WebMay 22, 2024 · A periodic function can be mathematically defined as: (8.1.1) f ( t) = f ( t + m T) m ∈ Z where T > 0 represents the fundamental period of the signal, which is the smallest positive value of T for the signal to repeat. Because of this, you may also see a signal referred to as a T-periodic signal.
