1 1 vote $\text{X}(t)$ is a stationary process with the power spectral density $\text{S}_{\text{X}}(f)>0$ for all $f$. The process is passed through a system shown below. Let $\text{S}_\text{Y}(f)$ be the power spectral density of $\text{Y}(t)$. Which one of the following statements is correct? $\text{S}_\text{Y}(f)>0$ for all $f$ $\text{S}_\text{Y}(f)=0$ for $|f|>1 \; \mathrm{kHz}$ $\text{S}_\text{Y}(f)=0$ for $f=n f_{0}, f_{0}=2 \; \mathrm{kHz}, n$ any integer $\text{S}_\text{Y}(f)=0$ for $f=(2 n+1) f_{0} , f_{0}=1 \; \mathrm{kHz}, n$ any integer Random Processes gate2010-ec random-processes signals-and-systems frequency-response gateway2010-ec + – admin 227 views answer comment Share Follow Add Sync Questions Print 0 reply Please log in or register to add a comment.
