Question
Let an input x(t) = 2 sin(10πt)+ 5 cos(15πt) +7 sin(42πt) + 4cos(45πt) is passed through an LTI system having an impulse response,
h(t)=2(sin(10πt)/πt) cos(40πt)
The output of the system is
Options :
2 sin(10πt)+ 5 cos(15πt)
2 sin(10πt)+ 4 cos(45πt)
7 sin(42πt)+ 4 cos(45πt)
5 cos(15πt)+ 7 sin(42πt)
Answer :
7 sin(42πt)+ 4 cos(45πt)
