Question
The time variations of signals are given as in 
and 
. Point out the true statement from the following.
- and are analogue signals
- A and B are analogue, but C is digital signal
- A and C digital, but B is analogue signal
- A and C are analogue but B is digital signal
and are analogue signals
The correct answer is: A and C are analogue but B is digital signal
As shown, we conclude that 
and are analogue signals but 
is digital signal.
