CT Fourier Series for periodic signals and some properties with proofs
- Fourier series of periodic signals
Function | Fourier Series | Proof |
---|---|---|
$ sin(\omega_0t) $ | $ \frac{1}{2j}e^{j\omega_0 t} - \frac{1}{2j}e^{-j\omega_0 t} $ | |
$ cos(\omega_0t) $ | $ \frac{1}{2}e^{j\omega_0 t} + \frac{1}{2}e^{-j\omega_0 t} $ | |
$ e^{\alpha t}u(t) $ | $ \frac{1}{\alpha + j\omega} $ |
