       energy per bit/noise power
       energy per bit/noise power density

Question 14.14. (TCO 7) If the noise level is increased in a data signal, the bit error rate (BER) _____.
(Points : 5)

       increases
       decreases
       remains the same
       decreases by two times

Question 15.15. (TCO 1) If two signals are mixed in the nonlinear operation of a device, the output will contain _____.
(Points : 5)

       the sum of input frequencies
       the sum and difference of input frequencies
       the sum and difference and harmonics of input frequencies
       a square wave

13. (TCO 7) The energy per bit to noise power density ratio is given by the ratio _____.
(Points : 5)

       signal power/noise power
       noise power/bandwidth
       energy per bit/noise power
       energy per bit/noise power density

Answer 13 is A

Energy per bit to noise power density is very important factor in digital communication it is known as \"signal power to noise power \" or well known as SNR

SNR = 1.76 + 6.02n

n is number of bit
