Determine . x(t) X(jω) = 0 g(t) = x(t)sin(2000πt) g(t) y(t) 2000π y(t) EENG 311: Signals and Systems Page 7 of 8 × lowpass filter y(t) cos(2000πt) g

Answer 1

hello your question is incomplete attached below is the complete question

answer : attached below

Step-by-step explanation:

let ; x(t) be a real value signal for x ( jw ) = 0 , |w| > 200
`\pi`

g(t) = x ( t ) sin ( 2000
`\pi t )`

`x_(1) (t) = (1)/(2) x(t) sin ( 4000\pi t )`

next we apply Fourier transform

attached below is the remaining part of the solution
