- A signal is a function of a set of independent variables, with time being perhaps the most prevalent single variable. The signal itself carries some kind of information available for observation such vibration, fatigue loading, etc. A discrete time signal is a sequence, that is, a function defined on the positive and negative integers. A discrete time signal can obtain from a continuous time signal with sampling then result in time-domain can transform to frequency domain with Fourier Transform. A phenomenon, called ‘leakage’ if a sinusoidal signal does not go through an exact number of periods within the sampling window, it can be shown in this research that the discrete Fourier transform of the sequence has nonzero values for almost all values of the frequency index.
