What is the significance of sampling in digital signal processing as seen in signal-time graphs?.
- A.It allows for continuous signal representation.
- B.It converts analogue signals into discrete values.
- C.It eliminates noise from the signal.
- D.It increases the amplitude of the signal.
Model answer
What a good answer should say
- It converts analogue signals into discrete values.
Explanation
Why this works
The evidence shows that sampling involves taking measurements of an analogue signal at specific intervals, resulting in a series of discrete values. This implies that the continuous nature of the analogue signal is transformed into a format suitable for digital processing.
Therefore, the conclusion is that sampling is essential for converting analogue signals into a digital format.
