GATE EC 2024 Set 1 Q10 — Random Processes

A white Gaussian noise $w(t)$ with zero mean and power spectral density $\frac{N_{0}}{2}$ , when applied to a first-order RC low pass filter produces an output $n(t)$ . At a particular time $t=t_{k}$ , the variance of the random variable $n\left(t_{k}\right)$ is $\_\_\_\_\_\_\_$ .

Consider a real-valued random process $f(t)=\sum_{n=1}^{N} a_{n} \: p(t-n T),$ where $T>0$ and $N$ is a positive integer. Here, $p(t)=1$ for $t \in[0,0.5 T]$ and $0$ otherwise. The coefficients $a_{n}$ are pairwise independent, zero-mean unit-variance random variables. Read the following statements about the random process and choose the …

Let a random process $Y(t)$ be described as $Y(t)=h(t) \ast X(t)+Z(t),$ where $X(t)$ is a white noise process with power spectral density $S_{x}(f)=5$ W/Hz. The filter $h(t)$ has a magnitude response given by $\mid H(f) \mid =0.5$ for $-5\leq f\leq5,$ and zero elsewhere. $Z(t)$ is a stationary random process, uncorrelated with $X(t)$ , with …
