2.x(t2)
3.x(t)
4.None
​

Answer 1

Answer:

1 x(-t)

is the answer..,..............,

Answer 2

Answer:

1. x(-t)

Explanation:

If the independent variable t is replaced by '−t' , this operation is known as time reversal of the signal about the y-axis or amplitude axis. This can be achieved by taking mirror image of the signal x(t) about y-axis or by rotating x(t) by 180° about y-axis. Hence, time reversal is known as folding or reflection.
