Question 723

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	1000 bauds/sec, 4000 bps
B	1000 bauds/sec, 500 bps
C	4000 bauds/sec, 1000 bps
D	2000 bauds/sec, 1000 bps

Question 723 Explanation:

Actually there is a typing mistake in this question. They given 1000 bauds/sec, 1000 bps but it is wrong option. So, we are corrected and given correct option.
Step-1: Important formulas to find a solution is
Bit rate=baud rate*no.of bits per signal
Baud rate(or signal rate)=bit rate/no.of bits per signal
Step-2:They are expecting to find bit rate. Given data, 1000 bauds(signal)per second and number of bits per signal=4
Step-3: Bit rate=1000*4=4000 bits per second.

Correct Answer: A
