Question

If the bandwidth of a signal is $5$ kHz and the lowest frequency is $52$ kHz, what is the highest frequency

• A. $5$ kHz
• B. $10$ kHz
• C. $47$ kHz
• D. $57$ kHz

Answer 1

Bandwidth = Highest freq. - Lowest freq.

Highest freq. = 5kHz + 52kHz = 57kHz.

Ans- D

thankuu good explanation

Answer 2

Bandwidth is the width of the frequency band.

BW=highest frequency-lowest frequency.

• BW=5KHz
• Lowest frequency=52KHz

so 5Khz=highest frequency-52KHz

or Highest frequency=(52+5)KHz=57KHz

Option (3) is correct.

Answer 3

57 Hz

Bandwidth is the difference between the upper and lower frequencies

Bandwidth = Highest freq. - Lowest freq.

Highest freq. = 5kHz + 52kHz = 57kHz
