Question:
What is the bandwidth of a signal if the highest frequency is 5 kHz and the lowest frequency is 2 kHz?
What is the bandwidth of a signal if the highest frequency is 5 kHz and the lowest frequency is 2 kHz?
Show Hint
The bandwidth of a signal is the difference between the highest and lowest frequencies present in the signal.

- 3 kHz
- 5 kHz
- 7 kHz
- 10 kHz
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The bandwidth $B$ of a signal is the difference between the highest and lowest frequencies: \[ B = f_{\text{high}} - f_{\text{low}} \] Substituting the values: \[ B = 5 \, \text{kHz} - 2 \, \text{kHz} = 3 \, \text{kHz} \]
