CT Signal
- $ x(t) = 1 + sin(w_0 t) + 3cos(w_0 t + {\pi \over 4}) $
This is a signal with period $ T = {2\pi \over w_0} $
- $ x(t) = 1 + {1 \over 2j}[e^{j w_0 t} - e^{-j w_0 t}] + {3 \over 2}[e^{(j w_0 t + {\pi \over 4})}+e^{-(j w_0 t + {\pi \over 4})}] $
- $ x(t) = 1 + {1 \over 2j}[e^{j w_0 t}] + ({-1 \over 2j})e^{-j w_0 t} + {3 \over 2} [e^{j w_0 t}e^ {j{\pi \over 4}}]+ {3 \over 2}[e^{-j w_0 t} e^{-j{\pi \over 4}}] $
