An analog signal carries 4 bits in each signal unit. If 1000 signal units are sent per second, then baud rate and bit rate of the signal are _______ and _______.
- A.
4000 bauds \ sec & 1000 bps
- B.
2000 bauds \ sec & 1000 bps
- C.
1000 bauds \ sec & 500 bps
- D.
1000 bauds \ sec & 4000 bps

Show answer & explanation
Correct answer: D
Solution:
Baud rate is the number of signal units sent per second. Given 1000 signal units per second, the baud rate = 1000 bauds/sec.
Bit rate = bits per signal unit × signal units per second. With 4 bits per signal unit and 1000 signal units/s: bit rate = 4 × 1000 = 4000 bps.
Final answer: 1000 bauds/sec and 4000 bps.
