Unformatted text preview: y ( k ) = sin( x ( k-1)) (b) (5 points) y ( t ) = sin( t-1) x ( t ) (c) (5 points) y ( k ) = sin(2 πk ) x ( k + 1) + sin(2 πk + π/ 2) x ( k ) 4. (10 points) Evaluate the integral Z 1 + + ∞ X m =-∞ cos(16 πt ) δ ( t-m/ 4) dt 5. (15 points) Sketch the signal x ( t ) = u (-t 2 + 5 t-4)-2 u (3-t ) + 2 u (2-t ) 6. A continuous-time LTI system has impulse response h ( t ) = sin( πt ). (a) (5 points) Is this a causal system? (b) (5 points) Is this a FIR or IIR system? (c) (10 points) Show that the output corresponding to the input signal x 1 ( t ) = x ( t-1) is y 1 ( t ) =-y ( t )....
