Question

1. (TCO 1) A signal that is a function of time has the following properties (or the following applies to it). (Points : 4)        It must always be electrical in nature.
       It can be either analog or discrete (sampled).
       It must always be periodic.
       It must always be aperiodic.

Question 2. 2. (TCO 1) A sinusoidal signal, 10 sin(?t), passing through an LTI system, undergoes a gain of 0.5 and a 90-degree phase lead. The resulting output signal will be mathematically described as (Points : 4)        5 sin(?t + ?/2).
       10.5 sin(?t
