Unformatted text preview: y ( t ) = tan1 ( x ( t )) , is the system linear? Is it invertible? (b) (2 points) If y ( t ) = 1 t R t x ( ) d is the system linear? Is it timeinvariant? (c) (2 points) If y ( t ) + y ( t ) = x ( t ) is the system linear? Is it BIBO stable? 3. Impulse Response An LTI system is described by the ODE y 00 ( t ) + y ( t ) = x ( t ) (a) (3 points) Compute the impulse response h ( t ) . Use your answer to determine if the system is BIBO stable. (b) (3 points) Use the impulse response h ( t ) and the convolution formula to compute y ( t ) when x ( t ) = e2 t u ( t ) . (c) (4 points (bonus)) Use Laplace transforms to compute the answer to the above items (a) and (b)....
