Unformatted text preview: t u ( t ) h 2 ( t ) = sinc( t ) cos(8 πt ) (a) Determine the frequency responses of these systems. (b) The signal x ( t ) = 4 + cos(4 πt )-cos(8 πt ) is an input to these two systems. Determine the signals we would see on the output. 3. Frequency response of an LTI system is H ( f ) = 2 + j 4 πf 4 + j 8 πf-(2 πf ) 2 . (a) If the response of the system is y = 2 te-2 t u ( t ), determine input x ( t ). (b) Determine impulse response h ( t ) of this system. (c) Determine the ODE governing this system....
