Unformatted text preview: copies of X ( k s ) (signifying aliasing), as shown in the left Fgure below. X p ( ) is shown in the right Fgure. X p ( ) is plotted below:321 1 2 3 1/Ts321 1 2 3 1/Ts 2/Ts X p ( ) (b) Plot X R ( ) = F{ x R ( t ) } . Solution: We have that X R ( ) = H ( ) X p ( ), where the Flter, H ( ) ampliFes everything in the range [3 2 , 3 2 ), and attenuates everything else to zero. The left Fgure below shows H ( ) and X p ( ) on the same axis; the Fgure to the right plots X R ( ).321 1 2 3 1/Ts 2/Ts Ts 321 1 2 3 0.5 1 1.5 2 R 2...
