ECE 301, Homework #8, due date: 10/30/2008 http://www.ece.purdue.edu/ chihw/ECE301 08F.html Question 1: [Basic] For a continuous time system with impulse response h ( t ), what is the formula of computing the frequency response H ( ). If h ( t ) = 2 - t U ( t ), what is the corresponding frequency response H ( )? For a discrete time system with impulse response h [ n ], what is the formula of comput- ing the frequency response H ( e ). If h [ n ] = 1 k = - 1 2 - k δ [ n - k ], what is the corresponding frequency response H ( e )? Question 2: [Basic] For a continuous time x ( t ) = 2 -| t | , ﬁnd out the Fourier transformation of x ( t ). (Hint: Example 4.2) Question 3: [Basic] For a continuous time x ( t ) = U ( t +2) -U ( t - 2), ﬁnd out the Fourier transformation of x ( t ). (Hint: Example 4.4) Question 4: [Basic] For a continuous time x ( t ) = cos(2 πt ) + sin(4 t ), ﬁnd out the Fourier transformation of x ( t ).
