Sketch graphs of the following continuoustime signals. Indicate whether each signal is even, odd, or neither. (a) x ( t ) = t sin( t ) (b) x ( t ) = u ( t ) u ( t 2) (c) x ( t ) = 2 u ( t + 2) 3 u ( t + 1) + 3 u ( t 1) 2 u ( t 2) (d) x ( t ) = u ( t ) u ( t ) (e) x ( t ) = sin( πt ) sin( π ( t 1)) (f) v ( t ) = cos 2 (( t π ) / 2) (g) w ( t ) = cos 2 ( t ( π/ 2)) (h) y ( t ) = ∑ 4 m =1 ( 1) m u ( 2 t + m ) 2. Sketch graphs of the following discretetime signals. Indicate whether each signal is even, odd, or neither. (a) x ( k ) =  k  (b) x ( k ) = 2 k [ u ( k + 2) u ( k 2)] (c) x ( k ) = 2 δ ( k + 2) + δ ( k 1) + δ ( k + 1) + 2 δ ( k 2) (d) x ( k ) = ∑ ∞ m =0 cos( πk ) δ ( m k ) (e) δ ( k ) = u ( k ) u ( k 1) (f) u ( k ) = ∑ ∞ m =0 δ...
