14.12 SUMMARY

• Almost all signals employed in circuits – periodic or aperiodic – can be expressed as the sum of infinite number of sinusoids. Finite energy aperiodic signals have continuous Fourier transforms, whereas finite power waveforms will contain impulses in Fourier transform along with the continuous component.
• Given an aperiodic waveform v(t), its Fourier transform is given by the Analysis Integral . Given a Fourier transform V(jω), its inverse transform is obtained by the Synthesis Integral . Various properties of the Fourier transform ...
