1. Simplify the following expressions involving the impulse and/ or shifted impulse and sketch the results: (a) g (t) = cos (7rt) (â€˜2â€”7; â€” 6 (t â€” 0.5)). (b) a(t) = ffoo6(7'â€”1)dT+rect(Â§)6(tâ€”2). (c) b(t) =6(tâ€”4)*u(tâ€”2). Solution (a) 905) = COS (7ft) (5(t )- 5(t - 0-5)) cos(7r0)6(t ) â€”cos (2)6(tâ€”0.5) 5 (t)
