Exam-style question
Try this first
A communication system has a baud rate of 2400 baud. Each signal change encodes two bits. What is the bit rate?.
- A.1200 bits per second
- B.2400 bits per second
- C.4800 bits per second
- D.9600 bits per second
Model answer
What a good answer should say
- 4800 bits per second
Explanation
Why this works
Bit rate equals baud rate multiplied by the number of bits encoded in each signal change: 2400 × 2 = 4800 bits per second.
