Abstract
In physical systems, dynamic behaviour can be expressed in differential equations. The results of any linear and time- invariant or differential equations are mostly composed of exponential forms. Exponential signals in the frequency domain or accurately analysed by an algorithm & the peaks of the discrete Fourier transform (DFT) results are adopted to obtain parameters that include amplitude, frequencies, damping and phases. Thus, these two types of exponential forms, if the damping is equal to zero, the mode is periodic & if the damping is not equal to zero the mode is aperiodic & thus it will decay to zero with time. If signal is periodic, the analysis method for periodic signal can be divided into time & frequency domain methods. If signal is aperiodic, it can also be divided into time & frequency domain method. Frequency domain can display the important messages that are hidden behind the signal; therefore the uses of such method can deal with computer system & quickly deduce solutions. The leakage is the most critical factor during signal parameters estimation. The leakage arises due to the side band frequency. Leakage is defined as the interference between side band frequencies. The amplitude, frequency, damping, and phase of exponential signals are analysed accurately in frequency domain by DFT algorithm, and the peaks of the discrete Fourier transform (DFT) result are adopted to obtain parameters that include amplitudes, frequencies, damping, and phase. The transform technique is used for analysis of signal parameters, Fourier technique is used for analysis of signal in frequency domain which gives frequency and phase related information of the signal.
