Step 1: Define the autocorrelation function The autocorrelation function \( R_W(t_1, t_2) \) of a random process \( W(t) \) is defined as: \[ R_W(t_1, t_2) = \mathbb{E}[W(t_1)W(t_2)] \] Show more…

Define a random process $X(t)=A \cos \left(\omega_{0} t+\Theta\right),$ where $A$ and $\Theta$ are independent random variables; $\Theta \sim \operatorname{Unif(}(-\pi \pi, \pi] ;$ and $A$ has mean $\mu_{A}$ and variance $\sigma_{A}^{2} .$ (That is, $X(t)$ models a signal with both phase and amplitude variation.) (a) Find the mean function of $X(t)$ . (b) Find the autocorrelation function of $X(t) .$ (c) Is $X(t)$ wide-sense stationary?

Stationary and Wide-Sense Stationary Processes
Given the random process X(t) = A sin(ω₀t + Θ) where A and ω₀ are constants and Θ is a random variable uniformly distributed on the interval (-π/2, π/2), define a new random process Y(t) = X²(t). Find the expected value E[Y(t)] and the autocorrelation function R_YY(t, t+τ) of Y(t). Is Y(t) wide-sense stationary? You may find this formula useful: sin²(ϕ) = (1 - cos(2ϕ)) / 2
