With more complex linear circuits driven with arbitrary waveforms, including linear circuits with feedback, poles and zeros reveal a significant amount of information about stability and the time-domain response of the system. Fourier Analysis vs. Laplace Domain Transfer FunctionsSep 10, 2021 · What's the Laplace transform of an independent DC voltage or a current source? I came across this while reading transients from a book. While solving a first order circuit in Laplace domain, it took the Laplace of a DC voltage source as V/s. I am not sure how it worked that out and there is not an explanation either.
