Unformatted text preview: (d) Determine the ±ourier TransForm oF y ( t ). (e) Determine x ( t ) by applying the convolution property and inverse ±ourier TransFormation. 3. ±ind the signal For which the ±ourier TransForm is: (a) X ( ω ) = 2 jω + 10 jω ( jω + 10) (b) Suppose x ( t ) is modulated with m ( t ) = sin( ω c t ) to Form the signal x m ( t ). Compute the ±ourier TransForm oF x m ( t ) For ω c = 100 π rad/s. (c) Next, x m ( t ) is modulated with cos( ω c t + π/ 4). Determine what flter is needed (i.e., determine H ( ω )) to retrieve x ( t ) From this signal. 1...
