Abstract
Signal is a quantity that carries informations of nature phenomen. The data’s which are presented on signal can be used to inforrm the characteristic of the phenomen. Nevertheless, signal is generally presented on time domain. For some cases, analysis of signals in time domain is too difficult. Here, we need to look at the problem from another perspective. Joseph Fourier, great mathematician, found that signal can be stated as linear combination of elementary signals where the coefficients of the linear combination were the spectrum of the signal and were function of frequency. Therefore, we can transform signal from time domain into frequency domain using fourier transformation. Moreover, periodic signal can be transformed using fourier series while aperiodic signal can be transformed using fourier integral. Keywords : fourier transformation, analog signal, frequency domain
