A digital binary communication system with data rate 110 bits/sec and AWGN p No= 0.01 uses the following signals to represent binary digits 1 and 0, respectively: s1(t) = 1.7, Osts 1/110 So(t) = - 2s,(t), Osts 1/110 Find the threshold, employed at the receiver, which minimizes the average probability error of the optimum receiver assuming the two transmitted signals are equally probable. The answer should be a number rounded to 5 decimal digits (the minus sign is accepted while other symbols like % are not)

A digital binary communication system with data rate 110 bits/sec and AWGN psd
No= 0.01 uses the following signals to represent binary digits 1 and 0,
respectively:
Osts 1/110
Osts 1/110
s1(t) = 1.7,
So(t) = - 25,(t),
Find the threshold, employed at the receiver, which minimizes the average probability of
error of the optimum receiver assuming the two transmitted signals are equally
probable.
The answer should be a number rounded to 5 decimal digits (the minus sign is
accepted while other symbols like % are not)
Find the average energy per signal assuming that the two signals are equally probable.
