t₂ ∈ ℝ and all Δ ∈ ℝ the following two conditions hold: Observation 5: A process is WSS if its mean is constant and its autocorrelation is a function of the time lag (t₁- t₂). The time lag is usually denoted by τ. From now on I focus on the WSS process since most real-world processes are modeled as
