The two inputs to an analogue multiplier are x(t) and y(t) with Fourier transform X(ƒ) and Y(ƒ) respectively. The output z(t) will have a transform Z(ƒ) given by
-
- X(ƒ).Y(ƒ)
- X(ƒ) + Y(ƒ)
- X(ƒ) /Yƒ

Correct Option: D
Multiplication of two signals in frequency domain is equivalent to their convolution in time domain.
