Let \({x_1}\left( t \right) \leftrightarrow {X_1}\left( \omega \right)\) and \({x_2}\left( t \right) \leftrightarrow {X_2}\left( \omega \right)\) be two signals whose Fourier Transforms are as shown in the figure below. In the figure, \(h\left( t \right) = {e^{ - 2\left| t \right|}}\) denotes the impulse response.For the system shown above, the minimum sampling rate required to sample y(t), so that y(t) can be uniquely reconstructed from its samples, is |
