6. Optimal Decision Threshold Prove that the bit-error rate (BER) given by BER == [erf (1 - 1/2) + (14/12) ID +erfc is minimum when the decision threshold is set close to a value given by = %1₁ +0,10 % +0₁ Hint: Use relationship between complimentary error function and error function and the fundamental theorem of calculus.
