Fourier Transform

Transforms a continuous-time function to a continuous frequency function to determine a signal spectrum
- Time -> Frequency

$$X(j\omega) = \int_{-\infty}^{\infty}x(t)e^{-j\omega t} \ \mathrm{d}t$$

Signal must be absolutely integrable
Can be determined using the integral definition or table [Fourier transform table (course handout)]
