Unformatted text preview: EE210-2, Fall 2011 Prof. Essam Marouf Linear Systems Theory (Transform Theory & Applications) ---------------------------------------------------------------------------------------------------------- Homework #7 To be Completed by Monday November 28, 2010 -------------------------------------------------------------- 1- a) Consider the discrete-time signal x ( n ) =[–1 –1/2 1/2 1 1 1 1 1/2] for n = [–4 –3 –2 –1 0 1 2 3] . Sketch x ( n ) vs n and use the result to sketch the signals i) x (3- n ), ii) x ( n ) u (3- n ), iii) x (2 n ), iv) x ( n-2) δ ( n-2), v) 1 2 [ x ( n ) + ( − 1) n x ( n )]-------------------------------------------------------------------------------------------------------------- 2- Is the signal x ( n ) = cos( π 2 n )cos( π 4 n ) periodic? If yes, determine its period. If no, state why not. -------------------------------------------------------------------------------------------------------------- 3- Determine the discrete-time Fourier transform (DTFT)...
