1. A signal that is a function of time has following properties or the following applies to it. (Points : 4) it is impossible to change the properties of a signal.
A signal can be modified by a system which applies a transformation to it.
an electrical signal can only be transformed into an electrical signal.
an electrical signal can only be transformed into a non-electrical signal.
6 sin(ωt – π/4).
6 sin(ωt + π/4).
5.5 sin(ωt – π/4).
y = x2
y= 2 x + 2
y = 2x
y(n) = , value at n = 2 is -1
y(n) = , value at n = 2 is 0.0174
y(n) = , value at n = 2 is 0
y(n) = , value at n = 2 is 0.841
No, it is not violated.
Yes, it is violated.

– 2δ(n-1) – 2 δ(n-2) + δ (n-3) +δ (n-4)
δ(n-1) – 2 δ(n-2) – 2 δ (n-3) – δ (n-4)
-2δ(n) – δ(n-1) – δ (n-2) + + δ(n-3)
δ(n-1) + 2 δ(n-2) + δ(n-3) +2 δ (n-4)
