Definition of ‘White SP’

---

Given a White SP:

e(t) \sim \operatorname{WP}(0, \sigma_e^2) $$ We can say that:

\begin{array}{l} m_e = 0 \ R_e(\tau) = \left{\begin{array}{l} R(0) = \sigma_e^2 &\tau =0 \ 0 & \tau \neq 0 \end{array}\right. \end{array}

$$So:$$

R_e(\tau) = \sigma_e^2 \cdot \delta(\tau)
