22.
The signal y(t) = x(- t) is __________ .
causal
non-causal
depends on x(t)
none of these
Answer: Option
Explanation:

For signal x(- t) to be causal, the original signal x(t) has to be anticausal.

Similarly for signal x(- t) to be non causal, the original signal x(t) has to be causal.

Hence response of x(t) depends solely on x(t) only.
