Question 1
|
A noiseless 3 kHz channel transmits bits with binary level signals. What is the maximum data rate?
|
3 kbps
|
|
|
6 kbps
|
|
|
12 kbps
|
|
|
24 kbps
|
Question 1 Explanation:
Bitrate = 2 * Bandwidth * log2(L)
where,
L = no. of signal levels
Since it is saying binary level signals, it means two level signals.
So,
L = 2
∴ Bitrate = 2 * 3 * 103 * log22
= 6 × 103 × 1 bps
= 6 kbps
where,
L = no. of signal levels
Since it is saying binary level signals, it means two level signals.
So,
L = 2
∴ Bitrate = 2 * 3 * 103 * log22
= 6 × 103 × 1 bps
= 6 kbps
Correct Answer: B
