integration - Simple exponential $\\|e^{j\omega t}|$ - Mathematics . . . I need help understanding this equation: $\int_0^T |e^{j\omega t}|^2 dt$ = $\int_0^T 1 dt$ = T 0-T is only one period, not all T $\ e^{j\omega t}$ is a periodic complex exponential and \omega is the angular frequency $\ e^{j\omega t} = \cos\omega t + j\sin\omega t$ My question is how $\ |e^{j\omega t}|^2$ got evaluated to 1 Thank you!

Why Fourier Transform uses the notation X (jw) and X (e^j Usually books (e g Oppenheim) use the notation X(jw) for the continuous time Fourier Transform and X(e^j$\Omega$) for the discrete time Fourier transform AFAIK the only parameter is w o $\Omega$, respectively Why they include these other parameters in the representation?
