Time-Domain Differentiation + dar( t + sX(se ds da sX(s); with ROC containing the ROC of X ( s) ROC could be bigger than the roc of X(s), if there is pole-zero cancellation. E. g 9te{s}>0 dt 8(t)+1=s. ROC= entire s-plane S-Domain Differentiation dx ta(t) ds, with same RoC as X(s)(Derivation is similar to d dt E te-(t ds s+ 9e{s}>-a S+aTime-Domain Differentiation ROC could be bigger than the ROC of X( s), if there is pol e-zero cancellation. E.g., s -Domain Differentiation
