| Abstract: | A special method of Fourier transform for a kind of functions,say,step function,Ramp function and other functions that can be turned into impulse functions by differentiation is described in this paper.Properties of impulse function are used to conduct Fourier transform in this approach.It makes Fourier transform of functions mentioned above simpler and easiler than direct integration. |
