"The transmitted symbols of a baseband system is {0, 1), in which the symbols are equiprobable. The noise power N_0 = 2e-6 W/Hz and
the energy per bit is 400e-8 W/Hz.; Assuming that the probability of error is maintained, determine the energy per bit in uW/Hz if the
noise power is increased to 3x10^-6 W/Hz."
