Question
Calculate the bit error rate. Input frequency is 64KHz. Channel Duration time is 10 seconds.Erroneous bits are 3000.Select one:a. 4.6875b. 0.078c. 0.0046875d. 0.046875
Solution
To calculate the bit error rate (BER), we need to know the total number of bits sent and the number of erroneous bits.
-
First, calculate the total number of bits sent. This is the product of the input frequency and the channel duration time. Since the input frequency is 64KHz (which means 64,000 bits are sent every second) and the channel duration time is 10 seconds, the total number of bits sent is 64,000 bits/second * 10 seconds = 640,000 bits.
-
Next, calculate the number of erroneous bits. We are given that this is 3000 bits.
-
Finally, calculate the bit error rate. This is the number of erroneous bits divided by the total number of bits sent. So, the BER is 3000 bits / 640,000 bits = 0.0046875.
So, the answer is c. 0.0046875.
