Question 1.1. (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 display an even symmetry.
       It must always display an odd symmetry.
       It may be periodic or aperiodic.
       It always originates from an electrical system. Question 2.2. (TCO 1) A sinusoidal signal, 20 sin(?t), passing through an LTI system, undergoes a gain of 2 and a 90-degree phase lag. The resulting output signal will be mathematically described as (Points : 4)        22 sin(?t + ?/2).
       40 sin(?t).
       10 sin(?t + ?/2).
       40 sin(?t Question 1.1. (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 display an even symmetry.
