Measuring Bit-Error Rate: You are attempting to measure the BER of a channel with a nominal signal swing, fl. V, of 500 mV. The BER is too low to be measured directly. However, when you add 15 m V rms and 25 m V rms of Gaussian noise to the channel, you are able to measure BERs of 10-8 and 10-4. respectively. What is the BER of the channel with no additive noise? What is the fixed component of noise, VN?
