Q#1 Fourier Transform GATE EE 2022 MCQ +2 marks -0.66 marks

Let an input x(t) = 2 sin(10πt) + 5cos(15πt) + 7sin(42πt) + 4cos(45πt) is passed through an LTI system having an impulse response,                

The output of the system is

2 sin(10πt) + 5 cos(15πt)

5 cos(15πt) + 7 sin(42πt)

7 sin(42πt) + 4 cos(45πt)

2 sin(10πt) + 4 cos(45πt)
