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. 0.046875d. 0.0046875
Solution
To calculate the bit error rate (BER), you need to divide the number of erroneous bits by the total number of bits transmitted.
Here are the steps:
-
First, calculate the total number of bits transmitted. This is the product of the input frequency and the channel duration time. Since the frequency is given in kilohertz (KHz), you need to convert it to hertz (Hz) by multiplying by 1000. So, 64 KHz = 64,000 Hz.
-
Multiply the frequency (in Hz) by the channel duration time (in seconds) to get the total number of bits. So, 64,000 Hz * 10 seconds = 640,000 bits.
-
Now, divide the number of erroneous bits by the total number of bits. So, 3000 erroneous bits / 640,000 total bits = 0.0046875.
So, the bit error rate (BER) is 0.0046875, which corresponds to option d.
