WebbConcluding Remarks 12 Examples 6.1 & 6.2 reveal that the same Laplace transform but different ROCs for the different signals x(t) and y(t) This ambiguity occurs in general with signals that are one sided. To see why, let x(t)=g(t)u(t) and y(t)= g(t)u( t).We may thus write The value of s for which the integral represented by G(s, ) converges Webb16 apr. 2013 · $\begingroup$ I don't think you understand correctly. If x(t) = Cos(3t + pi/4), it's periodic simply because it's a sinusoid. All sinusoids (i.e. cos(w), sin(w), e^(j*w) ) are periodic in the continuous-time domain (not necessarily though in the discrete time domain). You interpreted the formula wrong. Look at it again.
