Key Equations

$$\mathbf{C} = \frac{1}{n-1} \mathbf{X}'^T \mathbf{X}', \quad \mathbf{C} \mathbf{e}_k = \lambda_k \mathbf{e}_k$$
$$f_k = \frac{\lambda_k}{\sum_j \lambda_j} \times 100\%$$
$$X(f_k) = \sum_{n=0}^{N-1} x(t_n) \, e^{-2\pi i f_k t_n}, \quad S(f_k) = \frac{2|\hat{X}(f_k)|^2}{N \Delta t}$$
$$W(s, \tau) = \frac{1}{\sqrt{s}} \sum_{n=0}^{N-1} x(t_n) \, \psi^*\!\left(\frac{t_n - \tau}{s}\right)$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
