The bit error rate is calculated by dividing the number of bits received in error by the total number of bits transmitted within the same time period. A result of 10-9 is generally considered an acceptable bit error rate for telecommunications, while 10-13 is a more appropriate minimum BER for data transmission.
Bipolar-AMI in that zero represented by no line signal and one represented by a positive or negative pulse, one pulse is alternate in polarity, there is no loss of sync if a long string of ones, No net dc component, Lower bandwidth has Easy error detection
The message which the figure is representing that the graph is being drawn between the probability of error and
is defined as the ratio of Energy per Bit (Eb) to the Spectral Noise Density (No). It is basically a signal-to-noise ratio present at the input to a receiver and is used as the basic measure of how strong the signal is.
We can see the distance between the two signal to noise ratio lines is 3dB one line is of AMI, pseudoternary, ASK, FSK, and the other line is of NRZ, biphase PSK ,QPSK
