Unformatted text preview: FT ↔ G ( jw ) = 1 2 π [ X ( jw ) ⋆ W ( jw )] Then, G ( jw ) = 1 2 X ( j ( w-1)) + 1 2 X ( j ( w + 1)) We know that, G ( jw ) is rectangular window with duration 4, and it is a sum of two shifted version of X ( jw ) . Then, X ( jw ) is also rectangular window function with duration 2. Then, x ( t ) = 2 sin t πt 1...
