A single bit, equally likely to be 0 and 1, is to be send across an additive white Gaussian noise (AWGN) channel with power spectral density 
. Binary signaling, with 0
p(t) and 1q(t), is used for the transmission along with an optimal receiver that minimizes the bit-error probability.
Let 
, 
from an orthogonal signal set
If we choose 
and
,we would obtain a certain bit error probability
.
If we keep , but take
, for what value of E would we obtain the same bit-error probability?
